I'm getting the Ztube im thinkin which one of those should make more since, Also what bout something like a Nismo Cold Air Intake? Can get flodded and cause Hydroclocking

 

I believe the Nismo comes with a bypass valve (correct me people if im wrong). But if your getting a ztube dont waste your time buying the CAI from Nismo, your just gonna waste your money cause you only can have one or the other. I got pop-charger and ztube, i think its a great combo, reason why i went this way is cause it saved me money. I got the ztube from a friend for 20 bucks.
