i have proof that it would take a lot of water to suck up into the CAI to really screw up your engine. i went without a front bumper for over a week, with my CAI just chillin out in the open, through pouring rain, puddles, and i think even a little bit of snow. not a single problem.
Damn! and here I am, ******* popping my hood every time I wanna wash the car to cover the filter in a towel to keep it 100% dry. I feel a fool now. (nuts)
