ADD W1 Blow Off Valve Sound Plate Adapter for Volkswagen Golf MK7, GTI MK7/7.5, Audi A3 and Atlas
Upgrade your turbocharged Volkswagen or Audi with the ADD W1 Blow Off Valve Sound Plate Adapter and enjoy the aggressive turbo “Pshhhh” sound without replacing the factory electronic bypass valve.
The ADD W1 BOV Sound Plate installs between the OEM bypass solenoid and the turbocharger, allowing unused charge air to vent to the atmosphere during throttle lift. This creates a louder, more noticeable blow off valve sound while retaining the factory bypass valve and normal drivability.
Precision CNC-machined from lightweight billet aluminum and finished with a durable black anodized coating, the adapter is designed for strength, corrosion resistance, and a precise direct-fit installation.
