Damond Motorsports Oil Catch Can kits come with everything needed for an optimized Oil Catch Can system. An oil catch can is, in a sense, a filter for the positive crankcase ventilation system. The oil catch can(OCC for short) is used to tap and contain blow-by oils and condenced crankcase gases, that would otherwise flow throught the PCV system back into the intake tract, and allows for drainng of these fluids remotely. With the addition of an OCC kit, blow-by oils and gasses are routed to the OCC allowing them to be caputred. This prevents the blow-by from entering the intake system, where it would otherwise contaminate the clean air entering the engine. Cleaner air leads to better combustion, more power, better fuel ecnomy, less detonation, and less oily build-up.

What sets the Damond Motorsports OCC kits apart from the rest, is that we fully test our OCC components, to insure the best OCC set-up for your vehicle. Only high quility components are used in the Damond Motorsports OCC kits. Our OCC kits come tailored to fit your Mazdaspeed perfectly, for a no-hastle, quick and simple instillation. Each OCC kit includes a check valve, to prevent boost from possibly entering the crankcase, via the prone to leaking OEM PCV valve. The check valve allows for a 1-way opperation of the OCC system, keeping everything under vacuum, to better help vent the crankcase.

Included in each Damond Motorsports OCC kit:

• A Damond Motorsports OCC
• Quick-opening/high-flowing check valve, assembled/sealed with fittings
• Pre-cut oil and vacuum resistant hoses (black, blue, or red)
• Location specific bracket, and mounting hardware
• Slim stainless steel hose clamps
• Plenty of zip ties

The DM OCC features:

• Fully welded external aluminum structure. Welded on ports for a nice clean look, and to keep weight at a minimum.
• Layers and layers and layers of perforated baffle plates, allowing a large surface area for blow-by vapors to latch onto and keep the intake tract clean. The bottom layer features an oil scraper. Blow-by is forced directly onto the scraper, while the air is pushed around the sides of the can to the back of the lower chamber. The air is then drawn up diagonally through 3 more perforated plates, before it exits the top chamber.
• A super easy to use high flowing drain valve(drain plug on the MS6 V1 kits).
• Optional DM partial VTA valve and filter OCC set-up(recommended for high boost applications).
• Powder coated for enhanced durability.
