The air filters you have on your CAI's should repel *most* water. and most CAI's are pointed 'down', to avoid water getting to the intake without some serious force/pressure. In tests with mine, I had the house hose on the "JET" setting, and water BARELY came thru....at a 3" distance. In order to get that kind of water amount and force, you'd have to drive into a lake at about 40mph.
The ram air system I've designed (still doing prototypes folks, sorry for the delay) has 2-stages of moisture outlets so you won't get standing water, or forced water, issues. You'll be able to shoot a hose into the scoop, and not have any water going to the intake.
Water not only messes with air/fuel intake, but it can cause other problems as well, namely electrical shorting. With all the sensors and such under the hood, check to make sure they're dry or booted properly. Sometimes zip ties break (hot/cold/hot/cold/hot/wet/cold/hot, and so on).
