Cody, That's what Infinate is referring to. The Needswings CAI pulls cold air from out in front of the radiator. Which is technically out of the engine compartment. This unit pulls air from inside the engine compartment. Have you ever raised your hood after a short drive down the road? It get hot really quick and pulling all that hot air into your engine doesn't help at all. It's much better to stick with the original induction system.
