AEM Cold Air Intake Systems

Vehicle Specific

Part Number: 21-731P
Features & Benefits

The AEM 21-8011DP Brute Force Air Intake System produces horsepower and torque gains by replacing the vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Chevrolet C1500, C1500 Suburban, C2500, C2500 Suburban, C3500, K1500, K1500 Suburban, K2500, K2500 Suburban, K3500, Tahoe and GMC C1500, C1500 Suburban, C2500, C2500 Suburban, C3500, K1500, K1500 Suburban, K2500, K2500 Suburban, K3500, Yukon and Yukon Denali models. Air enters the system through an extra-large AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the original air box space and is protected by a heat shield which is designed to reduce intake air temperature and increase horsepower. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is easy to install with commonly available tools. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.
