The Ultimate 2.0T Diverter Valve Upgrade

If you own an Audi or Volkswagen equipped with the 2.0T FSI or TSI engine, you know the factory diverter valve is a common point of failure. The Go Fast Bits (GFB) DV+ Diverter Valve (T9451) is the industry-standard solution. This direct replacement valve is designed to handle increased boost pressures and provide significantly faster response times compared to the stock unit, ensuring your turbo is always ready to deliver power.

Why Upgrade to GFB DV+?

  • Reliability: Eliminates the common diaphragm failures associated with OEM plastic valves.
  • Performance: Faster valve actuation leads to improved throttle response and better boost retention.
  • Versatility: Designed for a wide range of VAG applications including Audi A3, A4, and VW GTI/Jetta.
  • Easy Installation: A true direct-replacement part that integrates with your factory solenoid.

Whether you are running a stock tune or a high-performance setup, the GFB DV+ ensures that your boost pressure stays where it belongs—in your intake. By maintaining consistent pressure, you will notice smoother power delivery and improved acceleration. This valve is the perfect upgrade for any VAG enthusiast looking to improve the reliability and performance of their turbocharged engine. Trust in the quality of GFB engineering and find your next performance upgrade at GGCRACING.
