07-18 Wrangler JK 3.6 Liter Crankcase Vent System Kit TeraFlex

The TeraFlex Crankcase Vent System Kit is designed to improve crankcase ventilation and help protect the engine from unwanted oil ingestion. The system incorporates a secondary PCV valve to better control crankcase pressure and reduce the possibility of oil entering the intake system during steep climbs, off-road driving, or other extreme vehicle angles. It retains the factory-style oil fill location for convenient maintenance and is engineered to integrate cleanly with the vehicle's existing engine components while helping reduce the risk of hydrolock and related engine damage.
