OEM Z-Tube and OEM AIR BOX W/HKS Drop in Here. And i am Happy. I had a AEM CAI for the 1st 58000 miles and just got bored with It.

 

all intakes on our cars do very little in the way of power. CAI, Z-tube, short ram, K&N, whatever it is, you'll be lucky to pull +3WHP. Maybe my butt dyno is not as finely tuned as other member, but i sure as hell cant feel an extra 3 hp. Go with what sounds best, which in my opinion, is the injen (short ram setup so you dont have to worry about moisture). I listened to both the stillen and the popcharger+z tube, and like the injen the most.
