Turbosmart Dual Port Blow Off Valve Black for 15+ Subaru WRX TS-0215-1018

The Turbosmart Dual Port valve is a hybrid-type BOV offering three BOVs in one. The Dual Port can be configured to vent to the atmosphere, back into the air intake or both! Plumb Back system for quiet, road-compliant operation, Supersonic for the race track, or Dual Port for the best of both worlds. Features a twist top design to allow for quick fine tuning of the valve. 

New Smart Port Technology:

The piston is extremely light weight and fast acting. It is also very durable.

The "check" valve trumped design helps keep dirt and debris out of the valve, this is especially useful due to its low mounting location on this vehicle.

It will also require far less maintenance and lubrication.
