Banks Ram-Air Superiority. Flowbench developed, dyno proven. Improves airflow by 31%. Enclosed housing keeps out hot, power-robbing engine air. Easy filter access for monitoring & cleaning. The Banks Ram-Air has an enclosed housing to keep out hot, power-robbing engine air and instead inhales cool, dense, outside air. Air flow has been improved up by 31% for greater power and MPG while helping engine run cooler and cleaner. The giant filter flows more freely than the factory's highly dense paper filter, and the aerodynamic shape eliminates restrictions. The Banks Ram-Air works seamlessly with stock sensors so not to generate trouble codes while also accommodating 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 its dirty, it requires replacement of the whole expensive unit!). The Ram-Air is triple validated before the name "Banks" is stamped on. We test, the other guys Don't. That's the Banks difference! US Patent #10,138,851 B2
