ALL THE PERFORMANCE, WITH OR WITHOUT THE SOUND!
Choose the sound for your Hyundai or Kia and combine it with effective operation.
The GFB Respons TMS is a diverter/BOV valve that enhances the Hybrid dual-outlet concept with a unique sound adjustment system. This enables infinitely variable adjustment of the amount of air returned to the intake system or vented to the atmosphere – much like adjusting the volume. By turning the adjustment ring, you can adjust the valve sound from almost inaudible to very pronounced.
GFB has more than 20 years of experience developing and manufacturing bypass valves and blow-off valves. The Respons T9011 is designed for effective charge-air management, good throttle response and reliable boost pressure retention.
