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!)
