OP. On a 5.0 an aftermarket CAI is for the most part , cosmetic. the stock induction system is more than capable of delivering 600 rwhp. As others have said, a good tune is worth much more than an air cleaner change.
True enough, some of the aftermarket CAI units look mean. It all depends on how much money you want to spend to have a CAI you can brag about.
