I just put in a 30 dollar filter/adapter off of ebay. The manufacturer claimed around a 7-10% increase in power...i thought this was bs, but after driving with the filter on, its amazing. I have incredible throttle response, and my acceleration has noticably quickened. its great!

 

take pics and post

 

will do as soon as i can

 

why kind of filter is it....r u planning on doing a cold air extension?

 

its a nifty little k & n, and i am intending to do a CAI extension...just dunno how exactly...its awesome though, and the neat noise it makes under throttle rules
