i have injen cai with injen filter it came with. and im thinking about upgrading filter for it. what gains would i get if any? will i notice anyhthing different(sound, performance)? and what kind should i get(not too expensive)? which size? how about those k&n-s filters off of ebay?

thanks,
Tae

 

hahaha, maybe a different sound, maybe...but not much otherwise...Monsterflow and apex'i filters are supposed to be the best... I would stick with the injen though...the intake is designed for that filter!
