I was looking at cold air intakes and was wondering which is better (as in HP gain) between the Injen RS cold air intake, K&N cold air intake , or the first AEM cold air(not the V2)? I really want the AEM V2 but I don't want to risk hydrolock. It doesn't rain that much where I live, but it's the rainy season right now. I know the K&N can be made into a short ram which is cool so I am leaning towards that one. But you can use a bypass valve with the AEM. When using the bypass valve, how much power will you lose? Thanks everyone.

 

AEM V2 hands down winner. dont ever use the bypass, worthless and turns your cold air into a short ram. just dont use your s2k as a swamp buggy. lates

 

AEM & INJEN are about the same. You must beware that the throttle repsonse will become more sluggish and not as responsive.
