I just bought the truck and saw that the previous owner pealed back the foil on the inside of the fender next to the intake box.
I know why he did it, I am just wondering if I should put it back. Anyone have issues with water coming in?

Mine came brand new with that foil falling down, I tore it out because it irritated me. So far I haven't had water problems, and I have had the hood under water.

I took mine off,Cuz i thought it needed more air. No probs at all.
