I have a 2016 gmc2500HD denali diesel, want to swap the stock hood for a RKS Ram air hood. Now I dont have ram air. I know there will be a lot of guys rolling their eyes but I'm not sure how this will affect the motor compartment when it rains or I go thru the car wash. Will the engine compartment get flooded out or does the ram air part have no affect with water? I'm thinking I just exchange the hoods and not worry about the ram air, just usr the OEM air set up on it now. Correct? thanks in advance for any info.
