The newly revised Perm Tuning plate is a complete redesign with some pretty awesome changes and features. To start, it's available in an unfinished version for those that like the raw aluminum form and also in wrinkle black powder coat with an awesome raw aluminum cutaway logo on the front. That's where the aesthetics stop and the function comes in. The OEM PCV valve is reused so you don't have to add an additional check valve in the lines. True factory fit makes for an easier installation and less complication. The secondary vent is now a banjo fitting that points straight down for hose routing convenience and clean fitment. The bolt holes are now set up so that you can reuse the factory bolts. Again, less complication, more function. The PERM Plate is made 100% in house in the USA, even including the banjo fittings. You're looking at the best PCV plate on the market. Better yet, the PERM Plate is the ORIGINAL PCV plate for the Mazdaspeed and Ford Focus ST engines. It was first to market and it's still the best.
Here's why you would need an upgraded PCV plate.
In stock form, the DISI MZR only has a single vent of crank case pressures when under boost: the valve cover. As power levels increase, so does crank case pressure, and thus the need to vent it. This PCV Plate helps achieve just this, by adding a second vented port right at the source of the crank case pressure, the bottom end. Rather than force said pressure to flow all the way up through the long block, into the valve cover, through the gamut of valve cover baffles, and finally out the valve cover port.... you'll have a dedicated port to vent right at the source. And with this billet CNC machined piece, you even get to maintain the OEM baffle design (integral to the block), as well as the OEM gasket. No messing with RTV. Included fittings provide a 1/2 NPT threaded boss (providing ample choice in fitting / hose selection), and it comes with included longer bolts to accomodate the added thickness. This plate really should be the first step in addressing crank case pressures for high power DISI MZR power plants.
