In recent testing this air intake system produces 11 max horsepower, 10 lbs. x ft. torque and out-flows the factory intake by 90%. This air intake system offers a washable/reusable "oil-free" synthetic conical air filter that directly mounts to a unique 3-angle billet filter adaptor that helps smooth the air transition into the intake tract for better performance. A one-piece black powder-coated heat shield and cover requires little to no assembly for a hassle free installation. The filter is constructed with 100% polyurethane for long life and multiple cleaning cycles.

5-1/2” Conical Pro Dry S Air Filter: This intake utilizes a huge, 5-1/2" conical Pro Dry S performance air filter for increased performance. This 3-layer progressive, synthetic material air filter requires no oils and cleans with soap and water for maximum convenience.

One-Piece Filter Housing: The air filter is housed in a one-piece, black powdercoated 16-gauge heat shield that keeps warm engine air out for maximum performance. This one-piece heat shield uses factory mounting locations and comes with all hardware for a hassle-free installation.

Black Aluminum Cover: An attractive black aluminum cover is included to keep temperatures down while providing ready access to the filter for servicing.

Billet 3-Angle Adaptor: A billet 3-angle adaptor is used to speed up the air flow for improved performance and throttle response.
