yEa skooter, you were way too cautious...45 mins? what you do, hot box the car. From what I've heard you really have to submerge the filter to get any water up there. Butred SE-R said:the general rule of thumb is if you cant see the top of the curb dont drive throught the water. most cai systems are not that low unless the car has been lowered.
best reccomendation is measure from the ground to the cai and then measure a curb and remember where that level is. if its lower than that then yer safe is its not better stop. or get an air bypass valve. aem sells them really neat too.
if you fully want to avoid the hydro-lock paranoia, just buy an AEM bypass valve for your CAI. Or better yet, has anybody seen the second gen bypass valves, the chrome ones? I don't exactly know who makes it but those are nice.
