This Stage 2 air intake system produces 15 max horsepower, 20lbs. x ft. torque and out-flows the factory intake by 41%. Includes a massive air filter, and a one-piece heat shield that requires no assembly. This intake system also features a powder-coated black tube that replaces the stock intake tract and directs increased airflow with improved volumetric efficiency for maximum performance. 5-1/2" Conical Filter: This intake utilizes a huge, 5-1/2" conical Pro 5R performance air filter 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. This one-piece heat shield uses factory mounting locations for a hassle-free installation. 3-Angle Adaptor: The 3-angle adaptor is used to speed up the air flow after the air filter for improved performance and throttle response. Dyno-Tested Intake Tube: The all-aluminum black powder-coated high flowing intake tube is designed to maximize air velocity and is dyno-tested and flowed using the latest engineering tools for maximum performance, mileage and throttle response.
