What does the Damond Motorsports PCV Plate do, and what does it offer?

The PCV plate is a fully machined replacement of the factory PCV oil separator plate, with a port machined to accept an OEM Mazda PCV valve and o-ring, as well as two additional large -10 ports, thus allowing you to run a variety of PCV and OCC set-ups. With this latest version we have added a baffle plate to help reduce the amount of blow-by out of the PCV plate. 

Incorporating a PCV valve port onto our plate means you are able to maintain the correct amount of vacuum on the crankcase, under all engine vacuum conditions. With the additional ports, you’re now able to easily and cleanly run dual OCC set-ups in whatever configuration that suits your car best to relieve excess crankcase pressure. The PCV valve is held into the the DM PCV plate with a retaining ring, allowing for easier install and removal of the valve.

Awesome quality, perfect fitment, can't ask for anything better

Mazdaspeed PCV Plate

Designed meticulously and the hardware speaks for itself. Recommended for anyone looking to upgrade and maintain their Mazda/Ford pcv system. Should be bought along with an OCC since you'd be in the vicinity during install. Buy it because it's shiny too.

Quality kit for your speed

Done as part of my valve cleaning, egr delete, and sending off the injectors. This is one of the best engineered pieces I have seen for a car. The pièce de résistance was 10mm bolts to replace the factory 8mm, its attention to details like that that makes DM products so great.
