The AFE Pro Dry S Stage 2 Magnum Force Intake System for your 2011-2016 GM Duramax LML has resulted in 30 max horsepower, 50lbs. x ft. torque and outflowed the factory intake by 48%. This system features a custom built intake tube that incorporates an additional sensor pad for the factory humidly sensor found in the 2013-2016 HD models. This system includes, a durable 18 gauge, powder coated heat shield and features a washable/reusable conical pro Dry S filter for maximum flow.
The Pro dry S air filter uses three layers of progressively porosity synthetic "oil free" media to provide maximum airflow for the best performance results. This intake system also features a heat-insolating roto-molded plastic tube that replaces the stock intake tract and directs increased airflow with improved volumetric efficiency for maximum performance. This is a direct bolt-on kit that requires no cutting or drilling on OEM parts.
One-piece heat shield :
The air filter is housed in a one-piece, block powder-coated 18 gauge heat shield that minimizes performance. The heat shielded attaches to the lower half of the factory air box to provide 4direct airflow to the filter.
Roto-mold tube:
