This allows the Damond Motorsports OCC to vent pressure when excess pressure is present in the crankcase. This option contains a VTA breather filter and check valve. The check valve allows one way flow of pressure out of the can, while the filter keeps debris away from the check valve. The filters are completely washable and re-usable.

The Damond Motorsports VTA option is perfect for high boosting K04's, BNR's, and other bigger turbo options.  

Note: Not compatible with MS6 OCC Stage 1 Location 1, and Focus ST Stage 1 Location 1 OCC kits.
