AEM Induction 21-8000DC Brute Force Cold Air Intake for 1999-2006 Chevy and GMC 5.3L and 6.0L

The AEM 21-681C Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Audi A4 models. Air enters the system through an oversized 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 intake tubing is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system was developed to accommodate the engine's factory emissions control devices including the mass air flow sensor. The 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 backed by AEM's Lifetime Limited Warranty. 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. View the 21-681C vehicle applications to determine the legal status for each vehicle. AEM's Performance Cold Air Intake Systems are tuned and dyno-tested to give your engine more power and acceleration by replacing the restrictive factory air filter, air intake tubing and air box assembly.

The AEM Induction 21-8000DC Brute Force Performance Cold Air Intake System is designed to replace the restrictive factory air intake components on select Chevrolet and GMC vehicles equipped with 5.3L or 6.0L engines. Its tuned intake design helps improve airflow to the engine, supporting gains in horsepower, torque, throttle response, and acceleration. The system is developed and dyno-tested for application-specific performance and is designed to retain compatibility with factory emissions control equipment, including the mass air flow sensor.

Incoming air is filtered through an oversized AEM Dryflow synthetic air filter located in the original air box area. The oil-free, washable, and reusable filter media provides efficient airflow while helping capture harmful contaminants. Depending on driving conditions, the filter can be used for up to 100,000 miles before cleaning is required. A protective heat shield helps reduce exposure to engine-compartment heat, while the mandrel-bent aluminum intake tube features a durable silver powder-coated finish.

The AEM Induction 21-8000DC intake system is backed by AEM's Lifetime Limited Warranty. Emissions legality can vary by vehicle and location; verify applicable federal, state, and local requirements before installation. The system is listed for the supplied fitment applications, including select 2002-2003 Chevrolet Avalanche 1500 models and 2004 Chevrolet Suburban 1500 models.
