Compact Blow Off Valve Plumb Back fits Subaru
Plumb Back BOV
Subaru Forester XT 2005-2007
The compact series blow-off valves are designed for direct replacement with Bosch or Denso standard valves. In contrast to other valves with plastic diaphragms, these valves are equipped with a precisely manufactured piston that fits intake into the inside of the housing. This eliminates the risk of these valves starting to leak after a short time. Due to minimal production tolerances, no O-ring is required to seal the piston, making these blow-off valves extremely robust, low maintenance and reliable.
The Plumb Back valve returns the air to the system.
