Dual Port vents both to the atmosphere and back into the air intake. Ports with sequential timing allow quieter operation during normal driving, while getting all the benefits of a vent-to-atmosphere BOV under race conditions. Easily converted to a full atmospheric or full bypass unit by using supplied port blanking plug.


  • Dual outlet-type BOV.


  • Fits most cars using the factory BOSCH or DENSO bypass valves.

Quality product

Arrived in timely manner. Item was not a direct replacement with my factory denso bypass valve. Needed some new oddly angled hoses because stock hoses were not angled.
