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.

Perfect Fit

Amazing craftsmanship, the quality is A1. Car didn't blow up

Doesn’t really work as an oem direct replacement

This plate is a direct replacement but the angle that the PCV valve comes out of the plate makes it almost impossible to use the stock pcv port in the intake. This plate is pretty much made for just using it with an oil catch can set up. I’m sure it works fantastic when you buy it with a catch can but it’s very frustrating when you just want to use the stock pcv port on the intake and now you have to fashion a rubber hose.l to make it work. I just wish that was in the product description. Think about that when buying this part.

More of the Same - Amazing Quality and Price

I've been a big DM fan for years and have many of their products on my 2010 Genpu. I ordered this since I needed to replace the PCV, and "while I was in there," well, you know... This is a great future-proofing mod for my long-term plans to build for 500+whp, and the newly included baffle and larger ports means I'll be venting extra crankcase pressure with ease. It's a top-notch product from a top-notch company. Matt himself has helped me to troubleshoot via the phone on more than one occasion. That level of customer service is amazing, and part of the reason I keep coming back for more DM products. I can't say enough good things!

It works good. I like it very much

One of the Best Pieces

Super clean and Beautiful product. Great price, quick shipping and one of the best pieces on the market for reducing crankcase pressure. Best part about it is the ability to run a dual can setup!
