GFB T9481 VTA Blow Off Valve - VW/Audi 2.0T FSI, Gen 1, Gen 2, Gen 3 TSI

By combining atmosphere venting with the proven performance benefits of GFB's ground-breaking DV+, the VTA delivers an aggressive blow-off sound, improved throttle response, as well as superior boost holding and reliability.

With its low-profile integrated solenoid and compact design, installing the T9481 is a breeze. Simply swap out your factory diverter valve with the VTA, and you’re good to go!

Key features and benefits:

• Blow off sound AND better performance
• Reliable boost holding
• Sharper throttle response, faster boost recovery
• Low-profile integrated solenoid for seamless installation
• Australian-made, backed by a lifetime warranty

T9481 is a direct bolt-on for Audi, VW, Seat and Skoda vehicles that have a Pierburg-branded diverter valve. For specific fitment information, please see the chart below.

Why choose a VTA over a “BOV spacer”? 

Whilst “BOV spacers” might offer a cheap way to get a blow-off sound, they fail to tackle the fundamental performance and reliability issues associated with the OEM diverter valve – all they do is redirect the vented air.

The VTA offers more than just sound. By replacing the OEM diverter valve you also get enhanced performance and reliability.

Reliable Boost Holding 

Despite some improvements in reliability by the latest generation of OEM diverter valves, the performance trade-offs continue to grow. By re-locating the diverter valve to the intercooler piping (as seen on the Mk8 Golf R), vehicle manufacturers reduce the risk of heat-related failures. However, boost leakage is significantly greater due to the plastic OEM diverter valve piston failing to seal on an uneven plastic seat.

The VTA effectively addresses this issue by incorporating an integral piston seat machined into its body, ensuring a reliable seal even on irregular plastic OEM seats.

Sharper Throttle Response, Faster Boost Recovery 

OEM electronic diverter valves are binary in operation – they’re either open or shut. Your throttle, however, isn’t. When you make small throttle adjustments, the binary operation of the factory diverter results in abrupt changes in power delivery, which is the very definition of poor throttle response.

GFB’s patented “pilot actuation” system allows the VTA’s piston to open and close progressively, thereby smoothing the power delivery during throttle modulation, and ultimately improving throttle response.

Unrivalled longevity, backed by GFB's Lifetime Warranty 

The combination of precision manufacturing, attention to detail, and robust materials means the VTA will last a lifetime. So does the warranty!
