ADD W1 Blow Off Valve Sound Plate Adapter for Kia & Hyundai 2.0T
Upgrade your turbocharged Kia or Hyundai with the ADD W1 Blow Off Valve Sound Plate Adapter and enjoy the aggressive turbo “Pshhhh” sound without replacing the factory 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 electronic bypass system.
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.
