This Stage 2 cold air intake system produces up to 12 HP, 11 lbs. x ft. torque and out-flowed the factory intake by 42%. Included in this kit is a durable 16 gauge, powder-coated heat shield and heat-insulating molded plastic tube that replaces the stock intake tract and directs increased air flow with improved volumetric efficiency for maximum performance. This system features a washable/reusable "oiled" conical air filter for maximum airflow . The one-piece heat shield requires little or no assembly and the filter is constructed with 100% polyurethane for long life and multiple cleaning cycles.
5 IN Conical Filter with Inverted Top: This intake utilizes a huge, 5 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 18-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.
