Combining both the Damond Motorsports Stage 1 and Stage 2 OCC kits for the Focus ST, the DM Stage 3 Focus ST Dual OCC kit encompasses the whole PCV system, to keep crankcase oily blow-by contaminates filtered.
Included in each DM Stage 3 Dual OCC kit:
DM Stage 1 OCC kit, with mounting location and hose color options
DM Stage 2 OCC kit, with VTA add-on option
The 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 condensed crankcase gases, that would otherwise flow throughout the PCV system back into the intake tract, and allows for draining 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 captured. 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 economy, less detonation, and less oily build-up on the valves.
