(I did a search and I could not find an answer to my question.) I have a homemade cold air intake setup which puts my K&n filter real low, like maybe 10 inches from the ground. I ran my fingers on it and it was really dirty and wet. I am afraid of getting water in the engine. I could get rid of the whole set up but I noticed a huge power increase when I installed it and i don't want to lose that. I remember reading somewhere about a screen of some sort that won't let water in. Anyone know what this is??? Anyone know what it's called and where I can find it??? Thank you.
