Specs:
aFe manufactures its air intake systems to enhance airflow and increase overall engine performance. The sealed design of Stage 2 Si systems allows for horsepower and torque gains while maintaining a stock appearance. The enclosed airbox also provides a quiet yet powerful sound. Stainless steel installation hardware is included.

A. Made from cross-linked, polypropylene, rotomolded plastic, the airbox is durable and easy to install; it simply replaces the entire stock airbox.
B. Specially engineered openings in the airbox and a built-in air scoop located underneath the air filter supply cold air to increase engine efficiency.
C. The cover is made from brushed aluminum, and it unscrews from the airbox for easy access to service the filter.
D. 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.
E. The heat-insulating, molded plastic intake tube replaces the stock intake tube by screwing into the back of the airbox, and its improved design decreases back pressure. It also includes a precision-tuned mass flow sensor (MAF) pad to prevent false "check engine" light warnings. All aFe intake tubes have raised stops that help to form strong connections and prevent slippage.
F. This intake system contains an aFe Pro Guard 7 oil-based air filter for ultimate engine protection. Designed for heavy-duty diesel and off-road Chevrolet Silverados, it performs well in all driving conditions, but it particularly excels in extremely dusty environments. Composed of 100-percent polyurethane on all sides, the filter withstands high engine temperatures. Five layers of progressively finer, medical-grade cotton gauze and two layers of non-woven synthetic polyester fabric with random porosity block 99.7 percent of dirt and grime from clogging your engine. These materials combine with a specially formulated oil coating to yield a high-performance airflow and extended services intervals. All aFe air filters are washable and reusable; cleaning and re-oiling are recommended once every 25,000 to 30,000 miles.


Each aFe product undergoes extensive dyno and bench testing to measure airflow and maximize gains, which are represented in performance charts that highlight the airflow benefits of aFe models over stock models. As demonstrated by this performance chart, this aFe air intake offers airflow gains of 101 cubic feet per minute (CFM) compared with the stock intake.

This chart illustrates gains of up to 11 horsepower (red lines) and 27 foot-pounds of torque (blue lines) with this aFe Stage 2 Si air intake when compared with the stock model.
