Just wondering, what filter set-up are you guys running with 4inch t4 compressor inlets. Compressor inlet on the driver side of course.

Looking for some ideas.

 

hks mushroom! yes they come 4 inchs.

 

damn, they come in 4inch configurations. wow.

only thing that concerns me is the foam. are there any paper filters like k&n that come in 4inch diameters?

 

Injen which are also K&N.

This is a K&N. I can get the part # if you want it.

 

woah! K&n has a 4 inch filter? Part number please..

 

Where did you get that flexible piping for your wastegate dump tube? How is it connected to the dumptube?

 

That's the one i use.

 

http://www.knfilters.com/universal/univrndtap.htm Here is the K&N site. They have quite a few different 4" filters with varying lengths. I got the dump tube pipe at Napa. It's just 1 1/2" flex exhaust pipe painted high temp gray. The clamp is a 1 5/8" exhaust clamp. You can get the pipe and clamp at Autozone or Napa.

 

K&N makes ones in up to 5 inches I think.

 

AEM makes a 4" filter as well.

 

K&N makes several 4" inlet filters with different lengths. I used one with a 3.5" length.

 

 

none, just a screen.

 

is there any benafit to moving the filter away from the engine kinda like a CAI idea? I have seen them setup both ways... filters on the turbo and some piped out of the way... Would it help for getting cooler air? or would it not even matter if your gonna use an intercooler anyway? Thanks

 

i have a 4" filter for sale, 10 bux plus shiping.....
