The Banks Power Ram-Air Intake System - 42215 is the best way to cool down your 2011-2013 6.7L Ford Powerstroke's intake air temperatures.
Enclosed housing keeps out hot, power-robbing engine air; inhales cooler, denser outside air. Improves flow up to 26% for greater power and MPG; helps engine run cooler and cleaner. The giant lifetime filter flows more freely than the factory's highly dense paper filter, and the aerodynamic shape eliminates restrictions. Works seamlessly with stock sensors to not generate trouble codes. Accommodates engine movement for greater durability.
Easy install; reusable filter is easy to access for monitoring and cleaning. (By contrast, the stock filter is difficult to access, not reusable, and when dirty, requires replacement of the whole expensive unit!) Lifetime warranty on filter element. Unit is triple validated before the name "Banks" is stamped on. We test; the other guys don't. That's the Banks difference!
