I've seen the pics of problemchild's dissected filter, and it shows that there is embedded dirt only partly into the red foam. There is no evidence of dirt in the later half of the red foam, and none whatsoever in the dark foam.


That said, if there was dirt passed through the media, there would be evidence of dirt deeper into the foam, pure and simple.


I still have not been able to detect ANY DIRECT light penetration through both layers of foam. I've seen what LOOKS like light, but is actually reflection from oil film, of an indirect light source. If you believe that you see light through the foam, then you should also be able to eclipse this light AND alter the shade with a piece of something colored. If someone wants to show me "the light" they are welcome to do so.





That's my story and I'm sticking to it...

Prove the holes.

PC doesn't have his filter any more from what I understand.

Interesting thought. I looked at the picture in the other discussion. I find it hard to believe that those "holes" are reflections in oil, since the filter is otherwise so dirty. I don't think dirty oil would reflect like that, and I don't think there'd be that much oil on the surface anyway.
BUT, your idea is excellent. Shine a bright light from behind and allow it to produce "dots" of light on a piece of black construction paper below. Then use your hand to interrupt the light.
I don't think problemchild can do that since his filter is now at Uni, cut in two. But for anyone else who thinks they have a similar problem, this would be a good, quick test.


Jim

When this first started, I checked mine. This is my post below. Although it looked like very small light, when I checked it as Kennedy suggests at that time on a piece of cardboard could not see any light. Checked my tubing at the MAF sensor again yesterday and still no dust or dirt. Mine seems to be working fine.

<TD class=text vAlign=top background="" bgColor=#fefefc> I checked mine today with only 2k miles since install, and yes I can see some small holes as shown by others. Checked tubing with clean white paper towel and no dirt or film. Could it be that under vacuum when engine running and with RPM that the filter compresses and closes these holes? Just a thought. </TD></TR></T></TABLE>

I'll check mine tomorrow provided it is sunny out. I am one who also "sees the light" and will try to see the light in a different way as John suggests.

If dirt had passed through this filter, wouldn't it stand to reason that there would be evidence that it had penetrated beyong the first 1/8" to 1/4" of the red foam? Sorry, but you cannot tell me that the thousands, if not millions of particles necessary to form a layer of dust somehow navigated through this element, particularly through a handful of pinholes without leaving a trail of distinctive evidence...

* If you believe that you see light through the foam, then you should also be able to eclipse this light AND alter the*shade with a piece of something colored.*
First, regarding eclipseing light through a filter.....Probably IMPOSSIBLE even with a clean/straight hole all the way through the media. The eclipse idea is used for viewing the sun through a pinhole made through an opaqe material that is THIN. Typically a piece of black construction paper or a sheet of alluminum foil. Trying to align a media that is an inch or so thick so that sunlight will travel PERFECTLY through a hole that is 200 microns wide is needlessly to say nearly impossible.
Have you ever had a narrow tube or pipe that was dark inside and tried to look down it using sunlight? Try as you may, it is VERY difficult to align a pipe PERFECTLY so that it is in PERFECT alignment with the sun, or any light source for that matter. A long straight pinhole in a 1 1/2 inch thick filter is likened to a 25 foot pipe at 4 inches diameter. I challenge anyone to line up that pipe with the sun so that sunlight reaches the bottom.
Regarding not seeing dirt in the second half of the filter, IF there are pinhole problems, the only place you would see the dirt in the top part of the filter would be if you cut the filter DIRECTLY along the path of that hole(s). IF the dirt was getting through the entire media then yes, there would be dirt in the deeper parts of the filter but that doesn't mean it would be immediately obvious to the naked eye. Microscopes are amazing and if you have'nt looked through one lately it is easy to forget just HOW MUCH is down there at that scale. I'd bet that any air filter would look like a farce if it was scrutinized with a microscope, EVEN AT THE "CLEAN" SIDE OF THE FILTER. SPICER

We may want to check to see if the air filter life indicator located on the air box is still intact. Mine has been knocked out every time I have changed my fuel filter (from the top). I know of three other people w/dmax's that are missing the indicator. My uncle went somewhere between 10,000 -60,000 miles before I pointed it out.


Hope this helps.

Sorry bout your internet problem,who knew ..... http://www.dieselplace.com/forum/smileys/Wink.gif


Thanks for the pic ,that is quite dense foam ....


How long did PC have that filter in service ?? Loks like they just seperated the two halves ....


What would be perfect is if the RED side was on the "clean" side that would be the proof ,huh ??


Whatcha gonna do no real way to prove one way or anouther .... Would I try a UNI ?? Yup if they had one fit on my AFE tube I would ...


Mac http://www.dieselplace.com/forum/smileys/Approve.gif

NEVER say NEVER.........

You assume the cut up no dirt here test is 100% accurate. When they wiped the filter in front of me the toilet paper was black. He said some dirt and mostly oil. So dirt was passing through.

I will offer this challange to anyone who says that filter didnt pass dirt into my intake tube.

CHALLANGE-----&gt;

We will clean my intake tube.
We will install a new same type of uni filter.
We will seal the filter box with some tamper proof seal.
I will drive the truck into high dust desert zones for 7k miles.
We will open the filter box at 7k miles.


If there is ANY dirt/sand/debris in the intake tube you buy my truck from me.

AND Post a full page ad in the Los Angelas Times that UNI builds defective filters that are crap.

Anyone want to put your money where your mouth is?

And why is kennedy getting pictures from UNI?
Those pictures dont prove crapola. I have pictures of the dirt in my intake that you so redily dismissed. Edited by: problemchild

Mackin, a number of weeks ago a guy posted here or over there that he put a UNI on his K&amp;N. The filter was # UAP-908 with filter wrap # 01-1122. The filter has a 4 inch connection. All dimensions are on the UNI site. I was wondering if it would fit in an AFE box. Is the AFE tube 4 inch? http://unifilter.com/automotive.htm


Steve Edited by: YZF1R

After reading all of this I checked my filter and what I observe is the same thing that John did. There is no direct hole but if you catch it just right you get reflections off of the oil. I used a spotlight on the other side as my light source. I have had mine on for about 4k miles and the intake tube is perfectly clean. I'll keep using mine until somebody proves it's no good.

OK nonbelievers, heres A challenge give it A try if your sure Problemchild is making this up, you'll have nothing to loose except if your wrong.


Problemchild did you get A call, or was this guy to busy sending pictures of your filter over the Internet to make the call he promised? I can't believe this is such A problem for any company to take care of.

What happens if you lose ?? http://www.dieselplace.com/forum/smileys/Shocked.gif


Mac

Problemchild gives the impression of being very offensive, and abrasive. Now he may well NOT be that way in person, but the impression given here is so. Not saying that this is how it was handled, but I am here to tell you, if you come in my door with all guns blazing you won't the reaction you get...





Mr Lewis has perhaps the best method of visual testing, although please be careful not to burn the filter with the heat that a spotlight produces.





PS. There was also some discussion of how the Dmax airbox must be assembled "just so" and I HAVE seen instances where a cover screw was not run in properly, and cocked leaving the filter unclamped. To the naked eye, it looks fine, upon closer inspection...

Myself, I'd like to see a little more said about proper filter installation and especially about the filter condition indicator being "knocked out".


I haven't been in the filter box yet as my 03 has only 12k, mostly on pavement, and the indicator hasn't moved from it's position when new.


Can't help but wonder WTF? PC sees the dirt,and knows the tube was clean when UNI installed. And JK sees his is clean, also with UNI, so is it a difficult thing to get reassembled correctly? Did PC FU?

These Filter Minder's are among the top 3 reasons for engine intake dirt. The units are very inexpesively made and in many cases leak horribly. In commercial applications it is the first item removed and sealed.
There have been more than one engine sanded/trashed as a result of a faulty Filter Minder.
George Morrison

of course the filter was installed wrong, and all the air boxes need replaced. couldn"t be a defective filter sold by a vendor on this forum.

JDTrip, your sarcasm is an inappropriate response to a legitimate question/comment made in an attempt to reach an accurate conclusion as to the very significant differences in this sitiuation and in no way furthers the conclusion of this very important issue.

dirty old man, my comment wasn't meant as sarcasm toward your post.I hope you get the info you need to properly install your uni. I won't need that info as I won't be buying one, now that I know how the manufacturer and the forum vendors react if you have a complaint.

Ignore that filter minder, they look pretty, but changing your filter based on that thing is like waiting until the oil light comes on to change your oil. I feel sure that your filters not real dirty with your milage and use, but I'd still check it at oil changes.

Would a pinhole not become quickly blocked with debris? I hope to take a look at mine this weekend but it doesn't make sense to me that a pinhole or a few would even let the amount of dirt through that is claimed.


I also don't understand why people are so quick to judge, be it a member, a vendor or a mfg. This is not UNI-Gate people! Relax. Let the data accumulate and a consensus will be reached. The inflammatory nature of some of the posts does nothing for the topic or the reputation of this site.

Mac http://www.dieselplace.com/forum/smileys/Geek.gif

No offense to anyone here! I think George has the best advise that I have seen in a long while on the board.


I just might remove the filter minder and seal mine. I have never seen one that ever moved. And if it ever got to the point that it would move I cannot imagine how bad you would be starving your engine for air.


OK I am out now...UNI, Amsoil, Paper, K&amp;N..It really doesn't matter to me.http://www.dieselplace.com/forum/smileys/Approve.gif

Problem assuming PC's problem is with the filter minder is he would have always gotten dirt if it was leaking ... Also his demeanor with UNI regardless of his tone here is pure speculation ... Just cause Kennedy talked to the Prez and the Prez said he PC was less then a gentelman,means nothing ... What would you aspect ?...? When your a consumer and feel you were dealt an inferior product and wanted resolve and was dealt frustration and "blamed" for the failure how many would just except that and move on especially when they took your merchandise for testing and said we'll call you ??


Also when installing the lid if it is half cocked as I've gotten mine before with the Amsoil install it's easier detected then by eye but by how the screws tighten ...


You would have to assume he is entirely unmechanicaly inclined to miss that and have no business popping the hood latch ...


Mac

So my take on this is UNI-Filters is one of probably a handful of companies in the world that has made a 100% flawless product since day one of production.

Is there a Nobel Prize Awarded for this?

If not, I guess JD POWERS might be giving them a call?

Dirtyoldman.
You buck the sarcasm but yet you ask if PC fudged up?

Heck! a monkey could install one of these!

PC stated without a shred of doubt in his mind that he installed it correctly. Let's leave it at that.

Would you want to be questioned like this and be accused of lying or being mechanically ignorant!
I bet you wouldn't stand for it!!

Let UNI do the right thing and give him whatever it is that he wants from them (apology, replacement etc...) or face the music with bad publicity.

I was contemplating buying one, still am, if UNI can fix the problem/narrow it down to a bad batch or whatever.

If I sold these, I would stop until they resolved the issue, not bash/blame it on the consumer (as at least one dealer of the UNI filter has). It's bad for business on UNI's end and the Dealers end. Maybe that dealer should go to bat for PC even if he didn't sell it to him. Now that would be going beyond the call of service.

While this dirt is being sucked through the pin holes before they plug, where do you think the dirt goes? Right into your engine, not A good thing. IMHO

Well, if it went into the engine, where did the dirt on the inside of the intake tube come from? At least the inside of the intake tube traps some of the dirt. http://www.dieselplace.com/forum/smileys/HiHi.gif

BOTTOM LINE- Nothing is absolutely, 100% effective


I feel for PC's situation and am somewhat dumbfounded at the lack of customer service from UNI. But on the other hand, there are always 2 sides to every story and somewhere inbetween is the truth.


If your filter, who cares what brand, is meeting or exceeding your standards, then stick with it until it doesn't or something remarkably better comes along.


I may be nieve, but I think the General knew this stuff and designed our engines to take a little abuse. I totally agree that the more stuff kept out of the engine the better and longer your engine will last, but reallity tells me that absolute outside air filtration will never happen with any filter or engine that needs outside air to run. Maybe we should all trade ours in for an electric instead, don't need air filters for them http://www.dieselplace.com/forum/smileys/Smile.gif.

I still don't get how that much dirt would get through a few pinholes. If that's how much accumulated on the inside of the intake tube, how much of the total volume that got through would it represent? 1% So the other 99% got through? Wow. I'm surprised it didn't sieze the engine!

sure the profit on that cheap foam is more, but what is best for the customer should come first, right? http://www.dieselplace.com/forum/smileys/Question.gif

Back to some facts;
due to the tiny passages and crevices the foam filters cannot be cleaned thoroughly and over time more and more as more passages are uncleanable and those passages plug up, this results one of 2 things:
loss of airflow or
air follows the path of least resistance and will find the other weaker open passages deteriorating them further making more open passages and allowing more UNfiltered air in.
So they either plug up restricting flow or let more dirt in. Also as a result of cleaning more new passages open allowing more unfiltered air...
And as foam filters age they deteriorate and can even let go catastrophically letting the dirty filter foam parts and all the dirt on the outside then get sucked in to your turbo and engine! http://www.dieselplace.com/forum/smileys/Dead.gif
I have seen this happen so would NEVER use foam on my vehicles.

DP


That much dirt in his intake tube on the walls should of shown some on the inside of the filter(looks clean to me) and I don't see how that much got through tiny pin holes. I feel there is more to the story.

If the dirt is passing through, then why would it make the filter dirty?


Diesel Pro,


I like the fact that you realize new threads are started here at the "Place" to take attention away from old threads. Not saying this is what JK was doing, just agreeing the tatic has been used. I have seen it done here before. They are also started by the same people to keep buisness up.


Bonehead,


If you go back and read all 8 pages of the 100% garbage thread, you will realize that due to the thread, several have inspected there filter tube and found dirt. My dirt came through a K&amp;N. Others dirt came through a UNI. Some found air minders and clamps to be the source. This thread and the garbage thread and the conversation thread, have taught us to take the time to verify the product is working properly and free from manufacturing defects. If your intake tube is clean you will never understand how it feels. Trust me, if you go to your 40k baby and see dirt in the intake tube from a part you installed, it is disturbing to say the least! Your comment about your review team getting silenced? That is disturbing as well. It is shotty R&amp;D that allows a site like this to thrive! It is shotty American R&amp;D that is allowing other nations to gain ground on what once was the greatest nation in the world!


Finally, if there are holes in any type of filter that allow abrasive particles to pass through, I guarentee these holes will get bigger with time. Erosion at it's finest!Edited by: Bronco

Looking at the filter it showes inlet side dirt part of the way through and none in the second stage of the filter. that much dirt don't you think some of it would show up in this area. Also I would like to see the back side of the filter to see if any dirt is on this side. Have you read his comment in the L A Dyno photo thread that this was all a joke.Hell of a joke I aint laughing.


Geno

Man there are some damn dense people here.

The post that EVERYTHING is fixed was a joke. The post that there is a problem is real.


Geeshhhhhhhhhhhhhh

Read a post PC wrote saying synthetic and dino oil will not mix cause I have a blown engine to prove it.http://www.dieselplace.com/forum/smileys/Ermm.gif


I've asked him twice, different threads, to explain this/provide proof. Still waiting for his response.

Old Man


Wonder if that was just a joke also.


Ain't Laughin

Geno ,


This is to simple. If you read the post which post was it and where is it currently at. If you read it then it should still be there in B&amp;W. Pretty hard to dispute once the post is provided for all to see if not then it is just hearsay nothing more nothing less

Geno,


I believe Problem Child made a fake post. It was a mauckry of the entire situation. He basically was pretending that he was totally incompetent, as many have hinted towards. I even responded to the post by stating that I was going to make a fake post as well. In this situation me and PC were thinking alike. The questioning in regards to correct filter installation was getting old. PC made a fake post trying to illustrate how stupid others were for even insiuating he could not install the air filter and properly inspect it. A monkey could install the filter corectly. A monkey could verify the filter minder and inlet tube clamps were secured.


We all need to shift our focus to the question at hand. " Is there a manufacturing defect or are all UNI's possibly defective. I say PC and a few others have filters that had a higher than normal hole count. It is just that simple. I would advise all DMAX owners to inspect there intake tube for dirt. If you find dirt then you should track down the source.


I once had a motor grenade on me. I had recently installed 20W50 racing oil and a can of Restore. Can I prove this was the cause? No. Have I always wondered? Yes.Edited by: Bronco

Doing my best to keep this off of the subj topic. Bronco, In 2 different threads PC stated that mixing dino and synth caused the engine to blow. No wondering, he stated it as fact. It was pointed out to him that they are 100% compatible and that oil companies have been selling blends for many years. He never replied with any proof or even conjecture. I don't know him or know anything about him other than what I can pick up from his posts. But, at this point, his credibility with me is pretty low.

Oldman,


I see where you are coming from.

Geno,


If the dirt is passing through, then why would it make the filter dirty?





We have a bingo !!!

Yep. More data needs to be gathered and then some fresh theories can be developed.

UNI USER

Mr. Bronco,


no matter what filter you may use, there will always be some dirt that passes through. (Otherwise, how does the air get through? duh) What you find in the intake tube is only a function of how long between inspections. My point is that if you use a good filter and change or clean it often you are way ahead of most folks. Your comment about "silencing" those that want to argue without end is off-base. Time to market is very important, and to wait around for consensus among a bunch of folks less skilled than yourself only empowers your competitors. I drive my truck on the highway like most of these folks. If I was driving my truck in a farm application I would certainly be a bit more concerned. But I'm not, and I doubt that you or most of the rest of these members are. Use a good filter and enjoy your wonderful, powerful, comfortable truck.

Hello Bone head,


Here is a link to another thread here at the "Place". It is something you might of seen here or on other wesites. It sorda summarizes the life of a formn.

Geno

BINGO

IF THE FILTER WAS PASSING EXCESSIVE AMOUNTS OF DIRT THROUGH THERE WOULD BE EVIDENCE OF DIRT AT ALL LEVELS OF FOAM DEPTH.





THERE'S JUST NO WAY ON GOD'S GREEN EARTH THAT YOU'D HAVE A HIGH DIRT THROUGHPUT WITHOUT HUGE AMOUNTS OF DIRT DEEPLY PENETRATING THE MEDIA! fOR ALL OF THAT DIRT TO THREAD THE NEEDLE THROUGH A HANDFUL OF SUPPOSED PINHOLES WITHOUT LINING THE FLOW PATH WITH DIRT IS IMPOSSIBLE. iF DIRT HAD A CLEAR PATH THROUGH, THERE WOULD BE THE IMPRESSION OF A TUNNEL IN THIS AREA. THERE WOULD BE DISTINCT SPOTS WHERE THE LAYERS WERE SEPARATED.





I'LL OFFER A UNI ELEMENT FOR THE TEST. CORE A NUMBER OF 1/16" HOLES STRAIGHT THROUGH IT AND SUCK SOME DUST THROUGH THE MEDIA. THERE WILL BE A DISTINCT DIRT PATH THRU THE FILTER IN THESE AREAS UNLESS YOU HAVE SOME SPECIAL TRAINED DIRT THAT CAN FLY IN A PERFECTLY STRAIGHT LINE...








GEESH! http://www.dieselplace.com/forum/smileys/Angry.gif

STOP YELLING!!! GEEESH!!!


You make a somewhat valid point.

But PC has admiited that he has put his truck through some rather extreme conditions The way he describes it (IMO)just short of taking handfuls of sand and chucking it at the face of the UNI while the motors running (my words not his)
If the pinholes "are" straight through then we won't need to buy your specially trained dirt ( how much is that stuff anyway? http://www.dieselplace.com/forum/smileys/Big Smile.gif )

As for as UNI cutting the filter. did they use a micro- scope and cut directly into the pinholes to see how far it penetrated (I doubt it) The penetration they are showing is through the filter as a whole I bet. It'd be pretty hard to cut exactly through the pin holes without disturbing something.

I do believe that after 7k of driving and some adverse conditions most filters (especially my K&N) will do what PC's has done.
Holes is Holes and it can't be safe. I choose not to take that chance and now so do many others. The jury is out until UNI can explain the holes. If they refuse to, I'm sure many more people will refuse to buy one. They should just suck it up and admit that something is wrong with the filters with the holes in them and replace them p-e-r-i-o-d !! And while they're at it contact people (at least from the same batch # and ask them to check theirs out and offer to replace if holes are found. It's simple cutomer satisfaction issues.

JK ask yourself this: Would you as a customer (and your not. because you use one & cause you also sell them)stand for this? Your answer would be biased. So you really don't have to answer it.

The ones taking a stand against the UNI are potential customers, including myself, That don't want to have issues like this.

GEEESH!!!

PepperidgeEdited by: pepperidge

You also have to wonder IF the Uni was heavily oiled resulting in a oil buildup inside the snorkel entrance .... Thus any teeney weeney particals of dust might have collecte making the problem look severe ... The oil itself would appear DIRTY but was the muke gritty ??


Would did the bottom of the airbox look like ,PC ??


By the way I pulled my AFE gauze setup off yesterday and it was squeaky clean ... So there ...http://www.dieselplace.com/forum/smileys/HiHi.gif


Mac http://www.dieselplace.com/forum/smileys/Geek.gif

Kennedy and the UNI prez are wrong.

How on earth can kennedy see microscopic dirt particles looking at low res pics over the web.

Did anyone use a microscope on the holes to see if they had dirt all the way through the channel?

My filter is cut to pieces now so we cant test it. Destruction of evidence? No filter no worries I guess.

Here are the facts........

Removed fairly new and very clean paper oem from box.
Inspected tube and and upper lid for dirt contamination, found none.

Compared UNI filter to old paper for size and fit.

Held UNI up to the sun, saw hundreds of tiny light holes.

Wondered if it would work ok

Installed it because everyone here said they were so great.

Made sure it had a wet bead of oil around the rubber.

Fit lid down and tightened bolts a little at a time until snug/tight.

Drove truck 7k miles.

During oil change removed filter lid to check filter tube (worried about all the holes in filter).

Found HEAVY dust and sand contamination.

Inspected wet seal around rubber for channeling dirt and/or leaking dirt around the filter, saw none. It was perfectly clean around the wet bead/seal.

Concluded contamination went THROUGH THE FILTER!

Cleaned tube and lid.

Bought new Napa oem paper and installed.

Drover 2k in dusty desert dirt road conditions.

Drove down to UNI to return filter and talk the them.

Walked out to truck and asked them to look at my tube after runnning the paper filter 2k in high dirt conditions.

Tube and lid were Completely free of dirt.



So you tell me. How did the dirt get there? Logic says it went trhough the filter. No dirt before uni and no dirt after would have you conclude the air ducting system is not leaking at the filter minder or etc...




It had to go through the filter. Others have said they had dirt as well. I am not the only one. Kennedy and UNi presidents test is flawed. I cant explain it.

You can still take my BUY MY TRUCK FROM ME CHALLANGE if your so sure your right.

If you are 100% sure your right what do you have to lose?

Money where your mouth is......

Why is it that you keep coming back if it bothers you so much.http://www.dieselplace.com/forum/smileys/Ermm.gif

It pisses me off to see some one wrongfully acused


Why did he put the filter in when it had so many tiny holes all the way through before it was ever run. at this point he should of contacted UNI to see if this was the way it is suppose to be. Would you put the filter in if you saw all the holes?

Geno,

He tells you why. b/c he heard they were so great, thought it was normal.

I wouldn't have, but he did.

Still ain't covinced me and others that UNI was wrongfully accused.

UNI is Rightfully accused of poor customer relations!

I know I may be a little late for some of this but..... I pulled out my KN&amp;N about a week ago when all this got me worried and mine was pretty clean. I had a few trace particles here and there in my air tube but nothing to get me worked up. I've got 15k on the filter now with one cleaning done on it. This is driven 90% ON GRAVEL as a farm truck. When I bought my KNN (right after buying my truck a year ago) I thought it was the only cold air setup for the duramax's. After learning of the UNI I was actually thinking about switching.... I think I'll stand pat for now. I cant bail on something that works for me considering my operating conditions...


Also, dont these filters REQUIRE a little dirt buildup to get them working? That was my understanding... I'll have to look at my papers but I'm sure KNN states that it filters better after a little dirt buildup....


Just my observations... I am NOT an expert by any means....


Jason

Nothing is absolutely, 100% effective

Oh yeah, you wanna bet? After asking more than once for UNI to send me data reinforcing their claim that their filters are the "best filters on earth", they sent me a data sheet from 1989 that says their filters are 100% efficient at the 5-10 micron dirt size!!!!

SO THERE!!!!http://www.dieselplace.com/forum/smileys/Wacko.gif SPICER


So what were the size of PC's dirt particles? After all, he did say that he drives in some severe dust conditions meaning that his air filter was subjected to some very small particles and a bunch of them.


This just brings me back to my other paragraph. If it works to your satisfaction, then go with it. As long as all of the variables were in the correct (or incorrect depending on your point of view) place, then PC had a 100% useless filter. Mine is working extremely well and I will stick with it.


Oh yeah, bought mine from Nick at nicktane.com and was pleased with his very prompt and courtious customer service.

I just checked you profile. I guess I could not expect anything more out of a firefighter when he speaks to a cop. You guys are definately overpaid and under worked (wax on wax off)http://www.dieselplace.com/forum/smileys/HiHi.gif. You'll never hear me complain about my salary, though.


Seriously though, I do appreciate your service and dedication to your community!!!!

I think Problem Child has brought an interesting discovery to the table. He found dirt inside his intake tube. I don't doubt this for a minute. I removed my 8,000 mile old UNI friday and replaced it with an AFE stage 2 at the dyno in a quest for power. I checked my tube and it is white glove spotless. SO WHAT! Two different people two different results. I recommend every one do a periodical check of their tubes to verify their filter's integrity. I bought mine from Kennedy and installed it and forgot about it until Friday. Yet Problem Child's observation weighed heavily on my mind. I thank him for bringing it to our attention.


PC. I wished you would have introduced yourself by your screen name at the Dyno Day I would have liked to talked with you some more about about sky diving. I also had my stock air intake assembly in the back of my truck including the UNI, I would have been grateful for you to show me your observations. The photo shopped UNI Banner in the Dyno pics was a little over the top though. That could get R&amp;D Dyno into trouble. It'd be cool if you could remove it.


I get your point your not happy with UNI. And it seems like maybe their customer service needs some improving. Thanks again for sharing with us your experiences. This is exactly what this type of forum is for. Now can we move on?

My friend with an '01 GMC D/A was changing out his air box to the UMP filter (didn't fit because of some little junction box or something in front of the EDU not allowing the air duct to come down and connect to the filter housing) and noticed upon removal of his MAF sensor that dirt had been seeping passed the MAF's o-ring. Perhaps PCs problem might include MAF leakage as well.

I recently sealed my air minder with RTV. Any tips on sealing the MAF?

STOP YELLING!!! GEEESH!!!



But isn't that what a little kid does when it doesn't get it's way... have a tantrum, WHAAAAAAAA! http://www.dieselplace.com/forum/smileys/Cry.gif

Facts are facts!

I would like to thank problem child also for bringing this to our atention, even though i already knew it, but also to thank him for his perseverance despite the attacks on his character and the barrage of attempts to discredit him and spin the topic.


Now to reply to Kennedy's comment on why there is little dirt in the open passages of the uni filter...
I will repeat since he just does not 'get-it' http://www.dieselplace.com/forum/smileys/Ermm.gif

"air follows the path of least resistance and will find the other weaker open passages deteriorating them further making more open passages and allowing more UNfiltered air in."

i will use CAPS so he maybe will understand better... [:rolleyes:]
LITTLE DIRT WILL STICK IN THE OPEN PASSAGES DUE TO THE AIR's SPEED (VELOCITY) WHEN GOING THRU THE SMALL PASSAGES VELOCITY INCREASES (like when you put your finger on the tip of a garden hose, the stream gets faster), AND THE FOAM MEDIA AS I POINTED OUT WEARS AWAY SO THE PASSAGES KEEP GETTING LARGER, YOU WILL NOT LIKELY SEE THE PASSAGES LINED WITH DIRT FOR THAT REASON! THEY WILL GET LARGER AND LARGER AND KEEP ALLOWING MORE AND MORE UN-FILTERED AIR THRU AND IN TO YOUR TURBO AND ENGINE!
ALSO AS SOMEONE POINTED OUT THE PASSAGES ARE NOT A STRAIGHT SHOT SO DISECTING THE FILTER ALONG THE PASSAGES FOR THOROUGH INSPECTION IS IMPOSSIBLE!

How thick is the Uni Dmax filter?

The reason i ask this is when you think about foam... It would be almost impossible after a certain thickness to have a straight line-of-site path through it.

If problemchild in fact has line of site holes, the foam either came that way or something went through it at high velocity, creating the holes.

What do we all think? Do they come new from the factory like that or do they develop? Edited by: hoot

Hoot


I run a different type uni (cone) but have seen the OEM style and the second layer is extremely dense, Something had to go through it to see sunlight or as he stated it was this way when he got it. If so there has to be a problem with the foam from UNI. Bad batch???


Geno

Nice sunny day so I checked my Uni this past weekend, well guess what it's back in the cardboard box it came in. Upon inspection there was 2 grains of sand in the intake tube that I found, but left no residue on a clean paper towel. On top of the filter close to the center, mesh side, was another grain of sand. The air intake box had some sand in the bottom also, where it's suppose to be. Pulled the filter and looked at the sun to find several holes that went RIGHT threw. It only had 3000 miles on and it's not even the dusty season here. I could not imagine how much I might find during the summer. I think that it needs another layer of a denser foam to work right, It's wayyyy to thin. It would really be nice if Uni stood behind their products, and did something to fix their non-filtering filter. They got me for 2 of them, and worse yet I have to tell my father to take the time bomb out that I spoke so highly of 1 month ago. Great http://www.dieselplace.com/forum/smileys/Confused.gif

Both of them are used, mine with 3000 miles and my father's around 5000/6000 miles.

SPICER,
Both of them are used, mine with 3000 miles and my father's around 5000/6000 miles.


The reason I ask is because it is well known that paper filters increase in efficiency as they gain mileage. There is speculation that foam filters may load and erode with useage. My intention is to test paper and UNI new, and used. If you are taking these filters out and plan on shelfing them, I would love to use them for testing. If I could only get one of them I would opt for the higher mileage one, but either would help out. Thanks for considering regardless. SPICER

Today was a bright sunny day so I deceided to pull my UNI and look at the sun. Guess what, I saw the sun though a bunch of little holes.http://www.dieselplace.com/forum/smileys/Cry.gif I only have 2,000 miles on this filter, so now I'm not impressed. Back in the box it went and the AC Delco went back in. I didn't see any dirt in the intake tube, but it hadn't been dusty around here lately. That probably was a good thing.

Hey Geno are you going to call those 2 above with leaking filters liars?

Hey PC,


What's the next questionable part we can drag through the mud? I am getting bored with the UNI.http://www.dieselplace.com/forum/smileys/Sleepy.gifEdited by: Bronco

I have a Uni filter that has not yet been installed.


I tried looking through it, and at first it did look like I could see light through it. But after looking closer, I realized it was oil sheen I was seeing and there were NO holes in mine.


I'm not saying that you aren't seeing daylight, but I'd like to see some sort of proof. Try taking a digital pic in a darkened room. Shine a flashlight (directional light source) from the opposite side, and take a pic of whatever light comes through.


Perhaps the high speed of the particles hitting the filter is putting holes through it after some mileage, but I'd like to see pics of actual light shining through in a darkened room to eliminate light reflected from the oil.

I think that a brand new filter, recently oiled, would show what you thought was oil sheen. After some use that oil will disappear and daylight will appear. I held up 2 screwdrivers behind the filter and could see them both. They were not perfectly clear but viewable. They cost me $100.00, believe me I want them to work, but they don't.

Spicer,
I will check with my father and his mileage and let you know.

CAJUN86, Thanks for considering. As I mentioned before, paper has better efficiency with use. Foam may be different and "aged" filters would be most useful.
