Hydro lock sucks ass, It don't even have to get into the engine. The water just soaks the filter to where air won't come in anymore. SO in turn the engine stalls. You consider yourself lucky let the water dry out for a few minutes and drive on. Trust me I go through this pretty much everytime it rains here. I hit a big puddle or drive in the ruts in the pavement. Nothing but a quick stall. The intake tube is like a straw. It doesn't take much force for you to suck a cold drink through a straw so consider how much air your engine is sucking. It gets even worse the lower the car is.

I'm looking for a cheap short ram now. I'm tired of the CAI always getting dirty and the above.
