2006-2007 Duramax Cold Air Intake Kit (42142)

Description

Fits

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 48% 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!)

The cold air intake kit features a big cotton gauze filter that needs less maintenance compared to other filters (unlike the small and disposable paper filter on stock models). It's oversized 7-1/8" outlet, sleek components, and sealed cold-air box effectively keep hot air from the engine out of the intake, resulting in a superior 48% increase in airflow compared to stock models. This not only boosts power and fuel efficiency but also decreases exhaust gas temperatures and minimizes black smoke. (Black smoke is a sign of wasted fuel - it may look cool, but it's not exactly usable power!)
