aFe Magnum FORCE Stage-2 intake system with a one-piece 3-1/2 in mandrel-bent aluminum intake tube powder-coated in matte gray, a one-piece 18 gauge powder-coated heat shield that uses the factory mounting points, and a 3-angle adaptor that speeds up airflow after the filter. The 8 in tall inverted-top conical 360 degree radial flow filter uses Pro DRY S three-layer oil-free synthetic media. It flows 55% more air than the factory intake and is rated at 18 hp and 23 lb-ft over stock. It bolts in with no cutting or drilling on factory parts.
