Drop in Filter
 

I'm getting a tune this weekend for my new exhaust and I want to change out the filter while I'm at it. I'm going FI down the road, so there is no need for a whole new intake now.

What are the good filters these days? I know K&N is one of the old standbys, but are there any that are better for a NA FA20 with a full exhaust on it?

They're pretty much all the same. Ft86 speed factory did some dyno tests. Just get the k&n on amazon with free shipping for $36 or whatever it is and call it a day. (Just clean off any excess oil)

HKS super hybrid filter 3-5 WHP gains should get a few more with the tune might even reach 190 whp
