PCV Baffle Plate for NC Mazda MX5 Miata by Radium

*Please see that the PCV Fitting is a straight bung, it is up to the buyer to determine if that will adapt to their set up or not*

The factory PCV setup lends itself to restrictions and failures. When you turbocharge these engines CRANK CASE PRESSURE is a major concern and this is one of the largest steps to help combat that. 

Features:
• Billet Aluminum PCV Plate with Baffles
• Aluminum 10AN ORB PCV Valve
• Aluminum 10AN ORB Plug
• Rubber 3/8" PCV Hose
• Spring Hose Clamps x2
• EFI-style Hose Clamp x1

Overview:
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.

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.
