The Engine Air Filter reduces harmful dirt particles from entering the engine’s air intake system where they may cause engine damage. The Breather Element helps filter the air pulled into the engine crankcase by the Positive Crankcase Ventilation (PCV) system or a metered orifice.
The PCV Valve or metered orifice regulates the flow of crankcase fumes into the intake manifold so they can be burned and help maintain proper crankcase pressure. As engine air filtration components become restricted, airflow is reduced, which could lead to poor acceleration, reduced engine performance, reduced fuel economy, oil leaks as well as other issues.
As part of the Kwik Kar 20 point oil change service, we visually inspect the engine air filtration system components and recommend replacement, as necessary.
We recommend air filter replacement once a year or every 15,000 miles. Interval may be shorter if vehicle is operated in dusty conditions.
