This is something i know alot of people are in question of.

Why do you think this way?

 

I personally would go with K&N. I've used their stuff in my other car and the quality seems to be great. From reading on these boards though, it seems that they all are viable options and its mostly a matter of preference. Oh, and if you care about CA emissions, then you should wait for AEM because the others aren't CARB approved. Keep in mind though, that the wait has been going on for a long time already... I'm personally holding off on getting any intake setup because it will most likely be useless once I get the supercharger (if THAT ever comes out...)

 

AEM if it comes out. But I am also waiting for the Supercharger
