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.

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!

PCV plate

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!


First off let me just say the shipping on this was ridiculously fast! I haven’t installed it yet but I know that it’s a fantastic product! Anything you get from here is going to be great! Definitely recommend everyone to get this and other parts from them!

Beautifully fabricated

The PCV plate looks great! I am waiting until the warmer months before installing, but by all accounts, the part looks top notch and installation should be fun!
