Oh,YEH!!,,As I am now rollin on the floor here and trying to compose myself to type,you said a hubcap from a Powerjoke and a emblem from a Duracrap,EH??,,Now I know what that undetermined metal was in my box,RICER PARTS!!!!!,,Ok,seriously here,,My sleeve has been removed since day one on all of my trucks and will do it again,,The amount of water taken in is not a problem,you can check it your self to ease your question,,Drive in the heaviest rain you get,pull into the garage and pull the top of the air box,,You'll see what I mean,,One thing it does do is allow the motor to not have to pull negative air from rear of fender,,Look and see where the air is coming from,and you can tell that no air or little is coming from the front,due to headlights and their design,,I myself am not sold on the Pshchotty deal as it is a poor design(again negative air,from cowl vents,which are not certainly a ram air setup)and who in their right mind wants to cut their truck up to install it,,I'll stick to the stock box and modify it its at least a proven piece and cleanly assembled... .
