I called K&N about my MAF sensor. I told them that I cleaned the sensor but it still faulted. They said it should not have been over oiled from the factory. Their tech rep told me to unplug the batteries for an hour and then reconnect. Apparently the computer can't compensate for the additional air flow. Is this true?

Sounds goofy to me.

This would be a good question for Eric.

I’ve had my K&N on for almost 60k miles and have never had a problem with it.

I know some guys carry a bottle of Absolute with them to clean off the sensor when out on the road.

not absolute everclear :drinking: Methonol works too, rubbing alky is a supposed no no since its not 100% alky but has lotsa other crap.

K&N is FOS. First pulling the battery wont reset codes ect. Second its not the engins ability to compensate for aditional flow.

I have a better solution. Take the K&N out, feel bad you wasted your money on a filter that gives no added performance AND lets in 49 times more dirt than a paper filter, then add the remaining oil you have onto the filter media, find your propane torch and light the overpriced piece of gauze on fire. Let it burn out, bury the ashes, vow never to be suckered by false advertising again, move on......Oh, don't forget to replace the filter before driving away....SPICER

Anybody running a Tymar filter set-up. Their popular on the powerstrokes, just curious.... here's a pic

spicer you're funny. I am going to put the stock setup back on. I was just reading your thread from the air test but which page are the actual results on. I've never seen one w/ 50+ pages before.

spicer you're funny.
I'm pretty sure he was serious. Did you ever wonder why K&N claims their filter works better the dirtier they get?:grd:

Saw the pic on the "Tymar filter set-up". Open element will suck in hot air defeting the purpose for more, colder air coming in. I'm not an expert by any means but doesnt seem to add any value.

absolutely true. Total aftermarket deception.

What a POS.!, and kills warranty at the same time. This BS should be illegal.

I put a K&N in my Dmax at 500 miles. I never had a problem with the MAF, but I took it out after I read the test comparison, I believe it was at around 20K miles. I ran these things for 25 years in all my cars thinking they filtered better than anything else. I never did it for higher flow, only for supposed better filtering. They may flow more air, but most of the time the stock filter is good for way more than the engine can draw anyway.

They may flow more air, but most of the time the stock filter is good for way more than the engine can draw anyway.

that is so exactly right. The avg draw is 400 cfm, and the pressure loss on the oem is absolutely negligible. The extra dirt it captures, is not.

I think the results are in that thread somewhere. The results were in a post or two in an unofficial format. The entire study was written and released on jbplocks personal web page. He has since removed it and sent me the disc with all the compiled data. At some time I would like to re-display it somewhere. I do not have a website. Maybe the forum administrators could put it somewhere on this forum, but there are vendors here that may not like that. Anyone willing to display it on their web page and advertise a link? SPICER

I will. If I can find it. Good study

I was told that using a K/N does not void your warrantee...btw I do not use one on my truck.........but lets get the facts straight for the people who do!

and kills warranty at the same time. This BS should be illegal.


Good God, chill.

It will not KILL YOUR WARRANTY any more than a FRAM or any other aftermarket paper or guaze air filter will if its found to cause a problem in your engine.

Can ANYONE show proof they have had a warranty claim denied because of running a K&N filter?

Probably not, but is that the point?

Nate, why do you use synthetic AND a fumoto?

Do not mean to excite or stir the pot.

"Every 3k is excessive, a waste and environmentally irresponsible. A lot of guys here including myself are going to 10k with synthetic, 5k at the minimum"

with all the silicon you can breath, that keeps oil fresh?

"Corvettes, Porshe's and other high end exotics require the use of synthetic oils in their engines, your warrenty is void if you use Dino oil. There must be a good reason."

No good reason. Oil and air never mix? Hopefully you don't live or work on dirt roads. If so, get an oil sample sent off after 5K. Then ask if it is wise to mix poor filtration with rich oil.

I hate these filtration threads. Like an election

Probably not, but is that the point?

Well, yes.

Why not? I change my oil every 10k

Sure you did!

I agree....:iamwithst

:beerchug:

This is one of those days I should have stayed in bed.

I guess I should have kept it short. I just don't see the point in using expensive oil, with lousy filtration.

Thanks for the warmth.

BTW, the "agree with stupid" remarks? You were agreeing with yourself, they were quotes from you, in recent threads.

I figure with a little common sense, if you find your warranty void for using dino oil, you might find your warranty void for throwing sand in the crankcase. I know that sounds dramatic and all, but poor filtration doesn't show up like a flat tire, it's a cumulative long and slow process of destroying the cylinders. Fortunately for GM, you will be out of warranty by the time it's a reality.

Well lets see, I was out of GM warranty after 18 months, (mileage) so you can sleep better tonight.

I doubt if there is much to worry about anyway, my ’97 Z71 was sold to a friend of mine with 160,000 miles on it 2 ½ years ago. It now has 220,000+ miles on it and has ran a K&N filter since the day I brought it home new. Has not burnt a drop of oil yet with oil changes at every 5,000.

My C5 Corvette has 60,000 + miles on it with a K&N since day 1, it also burns no oil. The air tube behind the K&N is spotless all the way to the throttle body.

All my vehicles see a fair share of gravel roads also.

I know it sounds a bit dramatic but they actually do a good job of filtering if you clean and re-oil them properly.

I have a better solution. Take the K&N out, feel bad you wasted your money on a filter that gives no added performance AND lets in 49 times more dirt than a paper filter, then add the remaining oil you have onto the filter media, find your propane torch and light the overpriced piece of gauze on fire.

Nice. :lol: :exactly:

My dealer here in El Paso sold and installed my K&N FIPK before I drove my 2005 off the lot,go figure.
This dealer has also recommended to GM that they buy back 4 2005 D/M because of the overheating problems,so far GM has bought back 3 of them.

After looking over the test data I have a couple of questions:
If you look at the data, report date 7/13 on the last page, in both instances regarding the K&N the "time, min" and "dust fed, gms" have some strange data that needs explaining. Restriction and time both reset to zero or less than zero after 4 minutes?
On the fine dust test, the dust chart shows 9.8 gms/min yet at 2 minutes 51.5 grams were fed? Also it was tested to 26.30 in h20?
Spicer, any ideas on this?

Curious

I was told that using a K/N does not void your warrantee...btw I do not use one on my truck.........but lets get the facts straight for the people who do!

I am getting ready to buy a GM certified 03 2500 D/A with a K&N cold air intake on it. I asked the liar, i mean salesman, and he said it would not void warranty.! doesnt mean much thoughCensored :lol:

If we could put a thread with Banks and K&N together we could see some real bashing!!:blahblah:

Where is this sensor located in the intake tube?:help:

Perhaps the MAF sensor is not contaminated with oil but sandblasted from all the dirt the filter let thru :)

Where is this sensor located in the intake tube?:help:

It is in the air tube just outside the filter box. Has some wires going to it. Mounted with two security star screws.

why argue about filters!!!!!!!! CLEAN THE MAF SENSOR , and see if it helps !!!!
