Description
AEM-21-8401DC Brute Force Intake System
The AEM 21-8401DC 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 Toyota Tundra and Sequoia 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 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 airflow sensor and engine breather hoses. 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 and it 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 21-8401DC vehicle applications to determine the legal status for each vehicle.
