This air intake system produces up to 4HP, 5lbs. x ft. torque and out-flows the factory intake by 71%. This system offers a washable/reusable "oiled" conical air filter with inverted top that directly mounts to a unique billet 3-angle filter adapter that directs the air 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 IN Conical Filter with Inverted Top: This intake utilizes a huge, 5-1/2 IN conical Pro 5R performance air filter with inverted top for maximum flow. This 5-layer progressive, oiled cotton gauze air filter provides maximum flow for increased horsepower and torque.

One-Piece Filter Housing: The air filter is housed in a one-piece, black powder coated 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.

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