aFe Stage 2 Pro Guard 7 Cold Air Intake System Chevrolet 6.6L Duramax 11-13

Advanced Flow Engineering, Inc. (AFE) produces high flow, high performance air filters & intake systems for the automotive industry. Founded in April, 1999, aFe was created to address an obvious need in the automotive aftermarket industry: a lack of choice for a high performance aftermarket air filter.

aFe is a team of engineers, machinists, production and sales people who believe in the product they design. Each has years of experience in their respective positions and together they work to ensure that aFe has the best product on the market. aFe�s purpose was not just to be another vendor that offers air filters, intake kits, diesel or gas exhaust systems but to pay attention to those finer details that set an aFe products apart from the competition.

aFe hits the market first with this brand new Stage 2 cold air intake for the new GM Duramax LML. This Stage 2 cold air intake produced an astounding 36hp and 63lbs. x ft. torque and outflows the factory intake by 33%! Enclosed in a durable, one-piece 16 gauge, powder-coated heat shield; this air intake system features a huge washable/reusable inverted cone conical air filter with Pro Guard 7 oiled media for maximum protection.

This intake system also features heat-insulating molded plastic tubes with a 3-angle adapter that replaces the stock intake tract and directs increased air flow with improved volumetric efficiency for maximum performance. The one-piece heat shield features two built-in grille side fresh air scoops and two rows of louvers that bring in additional outside air for a cooler, denser air intake charge.

This heat-shield requires little or no assembly and utilizes factory mounting points for easy, no-cutting or drilling installation. The filter is constructed with 100% polyurethane for long life and multiple cleaning cycles.

In recent testing, the aFe project LML picked up 2mpg (16.1mpg stock to 18.1mpg with intake).
