The Chevy Silverado and GMC Sierra are both well used and trusted work vehicles and have exceptional towing capabilities. They have long shared platforms and their engines follow suit. The 6.0L engine loaded in 2500 and 3500 models of the Silverado and Sierra is an excellent example of this similarity. Making 360 horsepower and 380 lb-ft of torque this engine is no slouch. Whether you're driving through dirty working conditions or just have the need for additional power, the 21-8031DC performance air intake system can help to make the difference. This intake is specifically designed for the 6.0L engine found in both the GMC and the Chevy. With an estimated 13 horsepower gain at 5100 RPM this air intake will interest both those looking for a performance gain and those looking for that slight towing edge.

AEM's Dryflow® synthetic material is used with this air filter. It is extremely durable with a high holding capacity for dirt, lengthening the amount of time between cleanings. The Dryflow media is covered and protected by a wire mesh of epoxy covered aluminum on both sides. The filter media used is unoiled, making the cleaning process simple and removing the possibility of over-oiling the filter. The cleaning solution is a mild cleaner and degreaser which simply removes the built up of dirt and grime so the filter can be easily rinsed clean and reused again and again.

The filter for this air intake is contained in an air box which pulls air from around the radiator core support to ensure near-ambient air temperatures. This has paid off with an estimated increase of 13 horsepower and 14 lb-ft. of torque to the wheels of a 2011 Chevy Silverado 2500 HD 6.0L truck at 5100 RPM. Additionally the removable top for this air box will make filter access easy and straightforward. The intake also comes with a Filter Minder to let you know when the air filter should be cleaned without removing the air box cover. The installation of this intake is simple and all required parts are included. Owners can even watch the air intake installation video on AEM's website. The 21-8031DC intake kit will not void your GMC or Chevrolet warranty and it is also covered by AEM's Lifetime Limited Warranty.
