i dont know for sure man. im not sure if this could've done it, but the night before i was driving and it was raining pretty hard and i didnt see this puddle and ended up going through it with the clutch held in. my CAI must've sucked some up cause my car stalled after i went through it. when id turn the key it wouldnt turn over at all, just click one time.(and the battery wasnt dead) So i waited around like an hour and it finally turned over and started up, ran a little sputtery at 1st, but then seemed fine. So i just went easy on it and drove it home slow. Then the next day is when the engine blew, after about an hours driving time.
