Ram-Air Intake System-2006-07 Chevy 6.6L; LLY/LBZ

The Banks Ram-Air Intake System delivers exceptional airflow and air density. Its large cotton gauze air filter requires fewer cleanings than competitive filters (stocks small paper filter is not reusable). With its giant 7-1/8 in. outlet, streamlined components and enclosed cold-air box that keeps hot engine air out of the intake, the Ram-Air flows up to 57 percent 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 in. bellows accommodates engine movement, which prevents component damage and prolongs service life.
