Go for a cold air intake unless you're scared of the hydrolocking (this happens to cold air intakes when the filter gets submerged in water like if you drive through a flood or some sort of freak incident). Hydrolocking ruins the engine but it is also extremely rare.

 

I'd go with a Fujita Cold Air Intake. I got one for my Accord. It was worth every penny. It gave me more power, looks good and sounds good. They use some quality stuff like silicone hoses, T-6061 polished aluminum tubing, T-bolt clamps. Everything for installation was included. Even the inside was clean. Some companies don't bother cleaning the inside of the aluminum tubing.

 

im still pretty loyal to the plain AEM CAI... as long as ur careful of puddles, it's worth it...then again....i put it on after a supercharger....so i noticed a bigger difference

 

how are the injen cold air intakes?
