The AEM 21-8408DP 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 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 chrome-like finish. This air intake system was developed to accommodate the engine’s factory emissions control devices including the mass air flow 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 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.

I have installed AEM intakes on previous vehicles and have always been extremely satisfied. The benefits on my 4.6 Tundra are more than I expected. Besides the better breathing and sound, the gas mileage is an unexpected plus. I have gained 4-6 mpg in hwy/city driving mileage overall. This was a great investment. I bought a second filter so I don't have any down time while my cleaned filter dries. Thank you again AEM!

I received my new intake in less than a week. Installation was a breeze and the instructions were perfect. I installed this intake on my 2011 Tundra with the 5.7L V8. My main goal was to improve gas mileage and my efforts were rewarded. I've noticed my biggest mileage gains in city driving (almost 4 mpg) and 2 mpg for highway driving... once your done having fun with your new toy. Sounds awesome, but not annoying. My ride to work is 400 mi/wk and this intake will pay for itself in less than a year. Recommend this product 100%.
