So, i recieved my new airbox from a member, and I need to get a few parts to compete the installation. Can anyone that has done the upgrade, do i need part number 7, or does the one from the 96 box work?

I did the change a couple of months ago and you will need the #7 they arn't the same, however I just lined things up and used metal screws into the fender to hold the airbox housing in place. A word of advice when you get a air filter there are two sizes of 97+ air filters and air box a heavy duty and light duty slightly smaller filter but still much more filter material area than the flat stlye of filter. I bought the heavy duty filter and couldn't get it to fit in the light duty housing.

I bought the box off of a member, and it came with the heavy filter.
Does the lid of your box tell you "use A1306C for severe dust conditions"? I might have the heavy duty box.

If that's true, then the "S" and "F" airboxes may be different due to the MAF on the "S" systems

I did the change also. All I did is use the one hole that does line up and it seems to hold up just fine. Not like its a high stress point. I think you can do without it.

Just my .02

it would be nice to find one of these airboxes for cheap...

I ended up paying $100 for the entire setup from a member minus $30 in parts I just bought from GMpartsdirect. The real kicker that made me spring was that he bought all parts brand new and never installed them.

My air box (small one ) says use 1300c or 1306c for severe duty. I'm presently running the Napa Gold 6441 heavy duty filter, but can't install the top so before it gets hot I will buy the 6440 light duty filter so I can use the cold inlet in the fender. The light duty is 6.5" dia. and is rated cfm of 250 the heavy duty is 7.25 dia. and is also rated for 250cfm they are both 11.12" long. The flat style air filter is only rated for 100cfm according to the NAPA filter guide so even the small filter is a huge improvement.

After I get it installed and run through the stock filter for a while, I will get one of the new Amsoil absolute filters.

Seeing that yours states that, I may have the small box also. Does anyone know the part numbers that are on the inside of the lid?

Hi guys,

I'd like to replace the stock OEM air box. Does anyone have a complete setup to sell?

Sincerely,

Rob :)

I have one of the flat panel setups I could part with, but you are probably looking for the cone style setup.

Jacob

Thanks Jacob,

You are correct, I am looking for a complete "cylindrical F-Style air box setup, 96 and later.

Sincerely,

Rob :)

Jacob: will this flat air box fit the 94? I may be interested

Just found this thread and haven't heard of this modification - what would be the benefits of my changing out the air box and flat-style filter on my 96 to the later air box and cylindrical-style filter? I'm guessing better airflow and possibly better filtration?

There is more surface area on the cylindrical filter than te flat panel. It will increase in airflow.

anyone know where to get the 97 air box complete set up?.....the HD one.

Same question here.

Junk yard, car-parts.com. A bunch of different places.

Jacob

i just phoned a wrecking place and they didnt' have one locally but a victoria parts place had one, and i just asked him what he thought one would go for and he said anywhere between $195-295:eek:. and thats canadian EH!!

do you need the rubber elbow from the turbo, because other than the turbo muffler and the filter change indicator, they do look a little different.

cheapest ones i found are all in ontario. 100-130 canadian. how much is shipping from there to BC, and are there high risks buying from any of these places.

I think that I would personally rather go to a junkyard and see what I am buying rather than having it shipped.

Hey Rigger... uh... thanks.

Rob :)

Your welcome. Now if you wanted a toasted front diff w/3.73's i could maybe help. Oh, btw, also have a DSG oil cooler on the way with new lines for the Blazer...... anyone interested in some stock lines, they will fit in a real small box once i get them out.

Wow thats highway robbery, I paid 35$ for round filter housing and hardware + a crossover pipe.

I guess I understand the reasoning behind a cylindrical filter as opposed to flat, laid out it would obviously have more surface area. But isn't the airflow limited by the size of the tube going to the turbo, rather than the filter? Obviously too small a filter would hurt, but going larger would not necessarily give you more airflow. Maybe potential airflow, but not without increasing boost, right?
Just a thought. Feel free to bash me on why that's wrong.
Also, I saw a bunch of pictures and parts list for building a homemade cold air intake a long time ago, but I can't remember where I saw it. Anyone have pics of one of these? IIRC it was about $20 worth of Home Depot stuff to make it. If I make my own maybe I could be convinced to part with my factory airbox.

I am not an expert on this, maybe you are right, maybe you aren't. All I know is that almost everywhere you read on here it says that the 97 airbox does flow better. Whether you need a chip, exhaust, higher boost, etc to really see the full potential I don't know. If you want to see an awesome cold air setup look at what jkauto is working on. Search for a thread titled cold air intake almost done (or something along those lines)

Jacob

I was checking my air filter last night, thinking about the ending of this thread and of those desparately seeking a 97 airbox.

Looking at the flat OEM filter, the size and the thousands of pleats, if you stretch it out there's about an acre of surface area there.

It is likely the round one does have more surface area, but I didn't have one to look at. They are apparently easier to get sealed up, but I see nothing wrong with the way the flat one seals.

I recall reading some fairly respected message board members over the years explain that the old flat style air box will flow more air than you could ever use in a 6.5.

Yet, it was upgraded, and the resultant model is no doubt better. I don't dispute this one bit, which makes it more desireable.

But not so much as to make it an urgent thing that you have to have. I suspect the performance increase with a newer style airbox will be = 0. Likewise the increase in fuel economy = 0, both give or take.

The main advantage I see, is that now, someone other than yourself will be able to take the filter out to check or replace it, and have it seal up properly when they are finished.

Ever go to a quick lube joint, or even a GM service oil service outfit, and watch the kid try to get a look at that air filter?

It's painful to watch, and that's an understatement.

Seem's he'd rather die than take that rubber boot off between the airbox and turbo.

If you don't go and help him, or tell him just not to bother at all, the rest of the gang will have the oil change done, and he will still be standing over the fender, now bathed in sweat with the thing half apart, and getting no closer to getting the filter out, or the lid closed to leave it in.

Just like mine except different filter.

Jacob

CHBob, guess I look at it this way (without urgency) the light duty round filter has 3800 sq inches of filter media, the HD round has 4200+ and the flat has 1900 sq inches. So I can put a round light duty AC Delco filter on with 20 times (literally check this out http://www.duramax-diesel.com/spicer/index.htm ) the dirt catching efficiency and still have 1.5 times the air flow as a K&N flat syle filter that cost 3 times as much and get dirty 3 times faster.

I have the benefit of cold air intake and since I use the old style rubber duct coming out of the turbo then into the 3 PVC pipe, then into my new style air box, there is little flow disruption 3" from airbox to turbo.

As far as milage goes, the flat panel filter is likely big enough when it is new but what about 6 months down the road, the round filter has the capacity to supply enough air even when dirty giving you better fuel milage and saving money because you only have to change the filter 1 time for every 5 or 6times you need to change the flat filter. Theoretically speaking, if the flat filter has 20% excess flow capacity the round filter has 120% excess flow capacity or 5 times the the ability to take on dirt before performance is impaired.

Tracy,

Good stats on the surface area of the filters, and other points you made.

Don't get me wrong, the newer style round filter is definitely better, bigger and more desirable, no question whatsoever. (and did I mention easier to change)

I was just suggesting to those who were searching the country in hopes of finding a newer airbox, that they should understand that they currently have an airbox that, equipped with an OEM filter, is willing and able to provide more air than they can ever use, providing the filter itself is clean, so take your time looking, when a deal comes up, grab it, but in the meantime, don't sell the farm to get one.

I read all the Duramax air filter study threads as it was ongoing, real interesting, and while there may or may not be differences in the Duramax and 6.5 filters, it convinced me that there is only one filter worth considering.

Hey crowne, did you just squezed the pi$$ out of the clamp to make it fit? Are you sure that you're getting a good uniform seal? I have this set-up (scrufdog secial) but havent put it on becaues the filter box end of the boot is smaller on the round style filter housings and I also need the bracket to attach it to the inner fender.

Oops. I see the muffler port in your pic. You have the correct ducting boot.

...Also, I saw a bunch of pictures and parts list for building a homemade cold air intake a long time ago, but I can't remember where I saw it. Anyone have pics of one of these? IIRC it was about $20 worth of Home Depot stuff to make it....

I think you are talking about a guy named CHEVYDAVE with a red burb. I think he has pics in his garage.

Will the older style rubber boot between the turbo and the flat panel filter housing connect to the elbow on the newer style filter housing?

I can use the old style rubber elbow and a pvc 90. I have not tried old style rubber elbow to a new stlye plastic 90+ degree elbow. If you need to know I can give it a try.

Actually it wasn't but I checked his out and like it. I woldn't go t oall the trouble of building that box, I'd just use my box and seal it to the fender like he did, but I'm liking that vent/grille thing. If only it were farther back where the newer trucks have them, then they really look sharp. Wonder how much air actually comes through that little vent, rather than just flowing past it. Hate to carve up a fender just for looks.

Give it a try and report back. Others here may be interested too. :cool: TIA

I gave it a try but doen't seem doable, approach angles are too different.

From 97 through what years is this style air box available?

Rats! Missed it!

Don't feel too bad, TurboTahoe. I won that filter housing. I've bid on several in the past, so I was thrilled to finally get one. But after reading this thread, I wonder if I bought an F or an S version. I didn't know they were different. Either should do what I want, but I always like to get the best. That way you can never say 'I wish I had done it better'. Best of luck in the future. You'll get yours...in a good way!

Rats! Missed it!

Keep an eye on the forum, looks like sstd595 and black sleeper are in the process of downgrading their air intakes, might make a deal, for their "junk" airboxes they are removing...

I missed it to, seems like the seller only ship to the US so I was blocked from bidding.:( Saved ya some money anyway!:)
