This Stage-2 cold air intake system resulted in 30 max horsepower, 50 lbs. x ft. torque and out-flowed the factory intake by 48% on the 2011-2015 Chevrolet/GMC Diesel Trucks. This system intake tube incorporates an additional sensor pad for the factory humidity sensor found in the 2013-2015 Silverado HD/Sierra HD models. This system includes, a durable 18-gauge, powder-coated heat shield and features a washable/reusable conical Pro-GUARD 7 air filter uses five layers of progressively finer oiled cotton gauze and two layers of finer porosity synthetic non-woven media to provide maximum airflow for best performance results. This intake system also features a heat-insulating 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 Filter Heat Shield:
The air filter is housed in a one-piece, black powder-coated 18-gauge heat shield that minimizes warm engine air for maximum performance. The heat shield attaches to the lower half of the factory airbox to provide direct airflow to the filter.
This system uses a C.A.D designed, dyno-tuned, roto-molded intake tube that achieves maximum airflow while maintaining a perfect fit. A sensor pad block-off plate is included to maintain fitment on early 2011-2012 model vehicles.
Large 7"x10" Oval Inverted Top Filter:
This intake utilizes a large 7"x10" oval base filter oval inverted top. A 5-1/2" diameter opening provides for maximum airflow. These 5-layers of progressively finer oiled cotton gauze and 2-layers of finer porosity synthetic non-woven media air filter provides maximum airflow for increased horsepower and torque.
aFe has developed this intake to provide a hassle-free installation that utilizes all factory mounting locations, minimizing the use of unnecessary hardware.
Note: This intake system is not CARB exempt at this time and is not legal for sale in California or use on vehicles registered with the California Department of Motor Vehicles.
