Overview

This Stage-2 cold air intake system produces 11 HP and 23 lbs. x ft. of torque and outflows the factory intake by 31%. Fully enclosed in a heat-shielding molded plastic housing; this air intake system features a washable/reusable conical air filter. The housing features auxiliary inlet duct for better airflow as well as an attractive black aluminum cover that provides ready access to the filter for servicing. This intake system also features a heat-insulating molded plastic tube that replaces the stock intake tract attached to a 3-angle adaptor with a built in mass air flow sensor pad that directs increased air flow with improved volumetric efficiency for maximum performance. The filter is constructed with 100% polyurethane for long life and multiple cleaning cycles.

Note: Does not fit the GM 2500/3500 09-10 with mechanical fan.

This intake is 50-state legal (CARB E.O Number D-550-13).

Bought and installed the AFE tonight for my 2012 Chevy Silverado 4.8L. Product looks great, but the air box holes weren't drilled correctly. I had to elongate the hole on the inboard corner to double the size to get the bolt to line up. Not a big deal, but I would think a good cad program measurement would prevent that. Next problem is the duct could be about 1 to 1.5 inches longer. The boots are barely long enough to reach the plenum (air box), and the clamps just barely have enough surface area to clamp around the flange of the duct and the plenum box. After installation, it looks great and sounds even better, but I will have to monitor to see if the boot slips off, which would permit contamination. Overall, it's a well made product, very easy to install, and all the hardware is durable and high quality. I would give it a much higher rating if the bolt holes and duct fit correctly.
