The wrath of Kaan

Think it might been said but yeah a bypass valve is a must with a AEM cold air intake.

well with the bypass i think it's been documented that you lose a few ponies due to the lack of flow with the valve and what not. i dont use one on my CAI, i just drive really carefully in the rain. thankfully the fact that im not lowered is a bonus too. if worse comes to worse and i seriously need to drive through a huge puddle, ill just pull out my pocket knife flathead, and disconnect the intake from the intake mani for the 20 feet i may have to ford through a river
