Blitz Blow Off Valve BR Release Type - Suburu Impreza WRX (2000-2007) & STI (2000-2021)

What is Return Type?

• The “Return type” is a type that returns the boost pressure that flows backward when the accelerator is off to the suction side through the hose just like the original.
• As with the genuine re-circulation valve, the air after supercharging is returned to the suction, so there is no problem even during vehicle inspection.
• It is possible to cope with high boost pressure, change the hardness of the spring, and open and close the valve with high response, which is difficult with a genuine re-circulation valve. 
  
• By simply replacing the attached screw type “Venturi Funnel”, you can easily change to the “Release Type” that is open to the atmosphere. 

*Some models cannot be used as "release type". Please refer to the vehicle type compatibility table.*
