anyone have the K&N air filter for the 04 max, if so, do you see any performance enhancements-vs-what it is supposed to do?? And where is the best/cheapest place to find them on the net.

thanks for all input

 

I didn't see any noticeable power gain from K&N drop-in filter. c'mon, you didn't
really expect to see a noticeable gain with $40 air filter, did u?
haha i'm just kidding....maybe there's like 1~2 hp gain if u dyno it.
no change in sound, either.

however,

this is where I found it cheapest so far....

 

I have a Stillen intake which uses a K&N cone filter. There is a slight gain in power, and it sounds awesome.
