The Banks Power 47172 Ram-Air Intake System for your 07.5-10 GM 6.6L Duramax delivers exceptional airflow and air density. Its large lifetime air filter requires fewer cleanings than competitive filters. With its giant outlet, streamlined components and enclosed cold-air box that keeps hot engine air out of the intake, the Ram-Air flows up to 66% better than stock. Improves power and MPG; lowers EGTs and reduces black smoke. Banks' unique 5" bellows accommodates engine movement, preventing component damage and prolonging service life. Designed to not cause fault or error codes; lifetime warranty on filter element.

Unlike our competitors, Banks doesn't just build-and-ship. Our Ram-Airs are triple validated before the name "Banks" is stamped on. We test; they don't. That's the Banks difference

5-Year Ltd. Warranty

Banks Optional Super-Scoop

Banks exclusive Super-Scoop is an add-on product to the Ram-Air Intake System. Super-Scoop connects below the front bumper, forcing a big charge of cool, pressurized ram air into the Ram-Air Intake's air filter housing. Because the air is drawn from outside the engine compartment, it has greater density and makes more power than warmer engine air. Rainwater and debris are funneled out of the bottom. Sold separately (see below).
