K&N filter w/ Z-tube OR JWT popcharger w/ Z-tube OR Weapon R intake..

WHICH IS BEST FOR SOUND AND HP!!!! i need help.. soo confused!

 

hp, none............sound injen or weapon R

 

i just got the Weapon-R. GET IT!!! but make sure you order direct from Weapon-R and get the upgraded 3.5" version. Also, i would advise to get a heat-sheild off of the JWT popcharger so there's not heat soak. You can get it from perfnissanparts.com or used from a member on here. They will all be around the same for HP. The WR gives the deepest sound at WOT. I've heard the popcharger and i have the WR, it makes the VQ sound even more beastly.
