Radium Engineering PCV Valves

Radium Engineering PCV valves provide precise crankcase ventilation control for custom and performance engine applications. Designed for installations where the factory PCV valve has been removed, relocated to a catch-can outlet, or was never included, these valves use an internal plunger to dynamically meter crankcase airflow according to engine load. Unlike a basic check valve, they help prevent an unwanted vacuum leak during low-load operation, close during intake manifold backfire to help keep combustible vapors from igniting in the crankcase, and seal under boost to stop positive intake pressure from entering the crankcase. Keep crankcase pressure under control and your boosted or naturally aspirated combination breathing properly with the Radium Engineering PCV valves best suited for your application!
