The aFe Momentum GT Stage-2 Si intake replaces the factory air box with a one-piece sealed housing and a dyno-tuned intake tube. Its 360 degree radial flow filter uses oil-free Pro DRY S media with three synthetic layers that is washable and reusable, and the housing keeps an auxiliary inlet that can be closed with the included urethane plug. The kit flows 19% more air than the factory intake and is rated at up to 8 hp and 11 lb-ft. It installs in about 15 minutes with no drilling.
