aFe manufactures its air intake systems to optimize airflow and increase overall engine performance. The open design of Stage 2 systems allows more air into the engine compartment, thereby boosting horsepower and torque. An increase in airflow also leads to a deep, throaty sound. Stainless steel installation hardware is included.

A. Made from 16-gauge, powder coated steel, the heat shield is durable and easy to install. Its single-piece construction eliminates the need for cutting or drilling; it simply replaces the entire stock airbox.

B. The three-angle adapter ring, located on the inside of the heat shield, bridges the connection between the air filter and the intake tube. Its conical shape helps to increase airflow velocity before air enters the intake tube.

C. The heat-insulating, molded plastic intake tube replaces the stock intake tube by screwing into the back of the heat shield, and its improved design decreases back pressure. All aFe intake tubes have raised stops that help to form strong connections and prevent slippage.

D. This intake system contains an aFe Pro Dry S air filter for a great balance of protection, performance and convenience. Designed for everyday gas and diesel Ram 1500s, it performs well in paved-road and semi-dusty driving conditions. Composed of 100-percent polyurethane on all sides, the filter withstands high engine temperatures. Two layers of randomly porous, synthetic fabric lie between two layers of progressively finer, medical-grade cotton gauze to block 99.2 percent of dirt and grime from clogging your engine. All four layers are dry and oil free, making it easy to service the filter. These materials yield a high-performance airflow and extended services intervals. All aFe air filters are washable and reusable; cleaning is recommended once every 25,000 to 30,000 miles.
