The Radium Engineering PCV Baffle Plate mounts to the engine block and replaces the factory plastic PCV plate and valve. Compared to the OEM unit, the CNC machined aluminum Radium Engineering PCV plate features an extra baffle to prevent oil sludge from entering the intake system without restricting air flow. Furthermore, there are two 10AN ORB ports machined above both aluminum baffles. 10AN ORB Adapter Fittings can be found HERE. NOTE: The OEM configuration kit (20-0327-01) is not compatible with all vehicles.
