A lot of people may disagre with me but, I think a bypass valve is essintial if it rains in your area, but it will also decrease some of the hp your intak is making.look out for the sniper

You don't need one unless you drive through flooding capable of completely submerging your filter in water. It rains a fair amount here in NC and I haven't hydrolocked yet...

How often do you drive through 16" puddles?

You don't need a bypass valve unless you drive a submarine.

It has been a pretty fierce debate at times, but it does appear the majority of people agree that you do not need one (I know I'm asking for it now)... For the record I just put a AEM CAI on and did not get one. It rained mighty fierce here in MO the last week, and I was forced to drive through some hellacious puddles, and nothing happened.

Once again, my 0.02 based off of much reading here at HCF.

Yeh, some great proof!

ive told this story before and i'll tell it again. the only time ive ever had experience with hydrolock (and considering my state is a fricken peninsula, surrounded by water, i got it pretty bad with water) is when my friend drove through a puddle in his old 95 lincoln. and let me tell you, this puddle was so deep that after it stopped thundering and lightning, little kids were swimming in it. i **** you not.

and you will lose 1-3 hp by putting on a bypass valve
