AFE Magnum Force Stage-2 Cold Air Intake System w/Pro 5R Filter Media - 01-04 Duramax LB7

This Stage 2 cold air intake system produces 12 HP and 28 lbs. x ft. of torque and outflows the factory intake by 42%. Enclosed in a durable 18 gauge, powder-coated heat shield; this air intake system features a massive 6" base x 7" height filter with a 4" flange washable/reusable conical air filter that improves airflow for increased horsepower and torque. This intake system also features a heat-insulating molded plastic tube that replaces the stock intake tract with a built in mass air flow sensor pad that directs increased air flow with improved volumetric efficiency for maximum performance. One-piece heat shield requires little or no assembly and the filter is constructed with 100% polyurethane for long life and multiple cleaning cycles. 4" Conical Filter: This intake utilizes a huge, 4" conical Pro DRY S performance air filter for maximum flow. This 3-layer progressive, non-oiled synthetic air filter requires no oils for cleaning for maximum convenience. One-Piece Filter Housing: The air filter is housed in a one-piece, black powdercoated 18-gauge heat shield. This one-piece heat shield uses factory mounting locations for a hassle free installation. Dyno Tested Intake Tube: The 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. This intake is 50-state legal (CARB E.O Number D-550-4).
