Had a Mazdaspeed CAI installed on my car last fall knowing the "small" risk of hydrolocking the engine. Just a small warning for those out there considering installing one: DON'T! My engine has to be replaced at $8100 because of water ingestion. Have only driven the car in moderate amts of rain, through no standing water or puddles whatsoever. The "disclaimer" on the installation instructions simply states, "If you anticipate traversing deep water, remove this system and replace it with the original equipment intake system. All warranties are null and void if water is ingested into the intake system."
The CAI didn't really seem to improve power much, although it did sound neat. Definitely wasn't worth the cost though. And I do mean this car was never driven through very much water at all--surface water only!
