KnN Intake w/ 4" inlet Part # ?

Anyone? I was looking for a greddy mushroom filter and gave up. Some folks say that there is a stubby enough KnN that will work with the older style manifold for the Gt35/40 kit. The one where the turbo sits a little more up and forward towards the rad.

Anyway, if anyone knows what the part number is can you hook a brotha up.

Thanks,
David

take measurements and find one that'll fit.

I'm not seeing on that site where I can find measurements to match my dims...

I have 7" clearance from the side and then 6" from where it attaches to the turbo forward.

It's highly dependent on the location of your turbo and everything in front of it...
http://www.knfilters.com/universal/universal.htm
We usually go for the taper ones.
http://www.knfilterchargers.com/search/univcone.aspx

Depending on clearances, we go with any of these:
RE-870
RE-860
RE-880
RC-4780
RU-5045

I see 5 on there that should fit your space requirements just in round tapered filters.
Are you concerned about the total filtering area?

You could always go with a 4” 90deg bend and put the filter on the end, if your setup is one of the average front mount arrangements.

Oddly someone was trying to convince me that that was the best way to have a air intake system not to long ago, hard to believe and illogical from what I know about fluids, but you could research that a little and keep it as one of your options if you are worried about surface area.

Do you have a pic of your engine bay? Specifically the area that you are concerned about?

Personally I would try and get it some cool fresh air instead of it just picking up engine bay heat, and used IC/radiator air. Is there any way to build a cold air box?

When I was thinking on going front mount I was planning on using the open touring oil cooler compartment and piping it up there, obviously that may not be an option for you. But it would be to your benefit to really think about getting fresh air to the intake.

PS what the hell dose that mean

Here's a photo of the space I am working with. You know, I would love to do something like routing the filter to somwhere cool but I have dual oil coolers and not sure where to stash it. I would just like to find a good fitting filter with the most surface area...Maybe even duct it between the FMIC and rad...Any ideas?. Oh, and the owl/bungee cord thing is from a ****** dumb movie called "Kung Pow" Master Betty is the villan...I laughed so hard I couldn't breathe. But then I have sort of a twisted sense of humor.

Ok, just ended up ordering RU-2510 for $35.90 including UPS ground shipping from 4Filters.com

I was thinking about routing it somewhere else instead of right on the turbo...Just gets to damn hot there...Any ideas?

Do you have place to put it? I want to make a cold air intake, but with the radiator and fmic, there isn't much room to route the piping. You could get some 4" aluminum tubing, or fiberglass or plastic, or that dryer house stuff that Max runs and make a CAI.

That filter looks kinda small for your application.

It does look kinda tiny. But I just installed it and I have about an inch and a half clearance before I hit the radiator. Maybe I can bump up to the next size.

I've got pretty much the same setup with an RU-2520, I'll see if I can find a picture for you and post it. It will help you get an idea how much room you have to work with.

True, but I think I have about 1.5" left to work with before I hit the rad...So I figure I will buy the next size up.

Thanks everyone!

That filter is sized for an NA 13B. It will create a restriction at high flow rates. Turbochargers multiply this restriction. Not good.

Could you install a cold air pipe, or maybe use a dual-inlet oval filter with one of the inlets covered?

I guess I could...It could run parallel to the rad....I get the larger RU-2520 first tho.
