Radium 06-15 Mazda NC PCV Baffle Plate

The Radium Engineering PCV Baffle mounts to the engine block and replaces the factory plastic PCV plate and valve. Compared to the OEM unit, the CNC machined aluminum plate features an extra baffle to prevent oil sludge from entering the intake system without restricting air flow. There are two 10AN ORB ports machined above both aluminum baffles. 

Because the OEM Ford PCV valve leaks at all boost levels, the kit with fittings includes Radium Engineering's own upgraded 10AN ORB PCV Valve which prevents boost from leaking into the crankcase. No permanent vehicle modifications are required.

NOTES:

• If using with the Radium Engineering Focus RS/ST catch can kits, select this option above. This will install perfectly with the PCV catch can kit and no other parts are needed. A check valve is not required.
• The PCV baffle kit (20-0327-01) is only compatible with the listed above.

PLUMBING

The baffle plate uses one of the 10AN ORB ports to plumb directly to the intake manifold with a PCV valve inline to control airflow to the intake manifold, just as the OEM plate operated. This PCV breather circuit is closed under load/boost by the PCV valve and does not flow to prevent boost pressure from being pushed into the crankcase. The crankcase breather from the valve cover to the air filter inlet pipe is responsible for venting the crankcase under load/boost. If the crankcase breather is not adequate for ventilation under load, the second 10AN ORB port can be used as a second crankcase breather to the air filter inlet pipe. This will allow more ventilation to protect the crankcase from building any pressure.
