The GFB VTA (Vent to Atmosphere) provides the signature blow-off sound for your turbocharged Audi or Volkswagen without the drivability issues common with generic atmospheric valves. Utilizing GFB's TMS (Turbo Management Solution) technology, this valve is designed to improve throttle response and boost recovery while replacing the failure-prone factory plastic diverter valve diaphragm.

Engineered to work with the factory ECU control, the VTA ensures the piston only opens when necessary, preventing the stalling or rich-running conditions often associated with simple blow-off spacers. The unit features a CNC-machined billet aluminum body and a precision-fit brass piston for superior pressure handling and long-term durability under high-boost conditions.

  • Manufacturer Part Number: T9401
  • Signature blow-off sound with factory-level drivability
  • Billet aluminum construction with brass piston for high-pressure reliability
  • Replaces weak factory plastic diverter components
