Banks Ram-Air Superiority. The Banks Ram-Air Intake System delivers exceptional airflow and air density. Its large cotton gauze air filter requires fewer cleanings than competitive filters (stock's small paper filter is not reusable). With its giant 7-1/8 inch outlet, streamlined components and enclosed cold-air box that keeps hot engine air out of the intake, the Ram-Air flows up to 57% better than stock. Improves power and fuel economy, lowers exhaust gas temps and reduces black smoke. (An indicator of unburned fuel, black smoke is power you can see but not use!). And Banks' unique 5 inch bellows accommodates engine movement, which prevents component damage and prolongs service life. Designed to not cause fault or error codes. Lifetime limited warranty on filter element. Available separately: new Super-Scoop optimizes the Ram-Air Intake's efficiency and power! NEW FILTER OPTIONS! Choose from the traditional red, dry filter or the all-new black, dry filter. Plus, you can even get an extra layer of filtration protection by adding a pre-filter to your order.
