The Damond Motorsports Stage 3 Oil Catch Can Kits are the ultimate in oil catch can and PCV control for your Mazdaspeed3. The DM Stage 3 OCC kits are intended for high horsepower engines currently running no OCCs or are looking to completely redo their PCV set-up. The Stage 3 OCC kits are a combination of our Stage 1 & Stage 2 OCC kits, where you can acquire all the needed components. If you're already running a DM Stage 1 OCC kit, check out our Stage 2 kits here. With the Stage 3 OCC kits there are a variety of PCV routing options you can choose from, to pick which option will best suit your engine's PCV needs.
In these diagrams, the routing for the Stage 1 OCC kit is in black and the Stage 2 OCC kit is in green. Routes 2 & 3 require a PCV plate, the Damond Motorsports PCV plate is available here. To further explain the routing options, their pro/cons, and what we recommend them for, please check out our PCV blog
