The AEM 21-8128DC 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 Ford F150 EcoBoost 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 air intake tubes are 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 intake air temperature sensor. The dual intake 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.

I like it. Shipping was super fast. Install was easy, instructions and hardware are good. My main reason to purchase was for increased noise, who doesn't love turbo noise?? The noise is certainly increased, but not a lot, it is hard to describe with words, but if you are looking for super loud turbo and blow off noise, this doesn't do it, but it does give you some more. Overall, I am happy with the purchase, it is a nice intake and being CARB legal is a requirement for me being in California.

Just wanted to drop you a line letting you know how satisfied I am about your product. Never would I have expected an increases over three miles per gallon. I went from about 17.4 to 21.1 miles per gallon in mixed driving, and from 24.1 to 28.1 mpg. I own a 2015 Ford F-150 King Ranch with a 3.5 Turbo V6. I shouldn't have to tell you of the amazing performance increase as well. Thank you, Howard

It really was quite easy to install myself - especially because the location is so easy to get to in the truck. It's an immediate difference and definitely worth adding. I highly recommend.
