Keep your car off when washing the car, then you don't have to worry about the water. Congrats on the dual CAI, that is one hot looking setup. I use the NealsWings single cai, which is my own home grown setup and has been awesome. It even has the hard aluminum pipe going through the side of the radiator support instead of the silicone ones. I think it makes a difference, but who really knows. Good luck with your new fun part.
