K&N for the na and TC cobalts is short ram.... no need to worry about water for that, unless your driving through rivers, ponds or anything like that. AEM is a CAI for the NA cars that goes down along the fender into the bumper. The Injen is a multi piece intake and can be used as a CAI or it can be taken apart and used a short ram.
