I had this on the car when I had a GT3076.

It fit in a 97 car with AC & PS.

see pic attached:
4" K&N Filter and 4" 90 degree silicone intake pipe.
There is a small piece of 4" pipe between filter and silicone to mate the 2 together.

I have a piece of 90 degree 4" aluminum pipe as well as a 4" coupler that I can include (my original plan was to use this kind of system, but it didn't clear the PS pump)

Seeing 18psi post about a filter made me think of posting this up, BUY THIS.

$120 shipped buys this well sorted air intake.

obo of course

 

So tempting.
I'll have to consult the bank account and get back to you on this.

 

No problem, I have quite a bit more into this but feel free to hit me up with an offer.
Or i'll trade for a 3" setup as well (I'm going to be running a gt2870 now)

 

obo & bump

 

selling only the 4" silicone 90 degree bend

cut to size, just buy a filter and go. 30 bucks and this is yours.
