The Banks Power 42135 Ram-Air Intake System for your 04.5-05 GM 6.6L Duramax LLY delivers astonishing best gains in airflow, air density and power. 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 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 and up to 23% better than others for greater power (up to +39 hp and +69 lb-ft more than a tuner alone), improved mileage and less black smoke. (An indicator of unburned fuel, black smoke is power you can see but not use!)
And Banks' unique 4-1/2" bellows accommodates engine movement, which prevents component damage and prolongs service life. Designed to not cause fault or error codes; lifetime warranty on filter element.
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
