Injen, AEM, and stillen are the preferred intakes around here. akuma makes a great looking piece too. all designed very similar. all are similarly designed and cost about the same. probably best bang for the buck TRUE cold air systems
if u wanna drop a little more coin u can go with the new litespeed titanium intake system that just came out
now if u really wanna get the jdm lovers nut swinging around here, u can go with top secret. but those are waaaaaay pricey
