With a CAI that was designed for the Focus you run near 0 Risk of hydro-lock unless your driving thru a foot and a half of water. Ive driven thru a hurricane with mine and it never even hiccuped. The filter for most CAI's will sit behind the drivers side FogLight. the bottom is protected by the front fender it covers the filter from road Spray.
So again unless your driving thru 1.5 feet of water don't worry. mines been on for 50k now and its never been a problem
That's exactly what CAI companies want you to think. But actually, water hides in tall grass on the side of the road and actually tries to hydro-lock your engine when you drive by. True story.
