T9481

The T9481 is a performance blow-off valve solution for the late-model VW, Audi, SEAT and Skoda vehicles.

In summary, if you know your GFB valves, this is the same as the T9451 VTA but with an integrated solenoid valve for a lower stack height and greater engine bay clearance.

If you want sound with your performance (or performance with your sound!), GFB’s T9481 VTA delivers!

By combining atmosphere venting with the proven performance benefits of our 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. Just swap out your factory diverter valve with the VTA, and you’re good to go.

Reliable Boost Holding
Despite some improvements in reliability by the latest generation of OEM diverter valves, the performance trade-offs remain. There is no escaping the fact that the moulded plastic valve mechanism of the OEM valve cannot reliably seal boost pressure. The VTA’s CNC-machined aluminium and brass valve components, combined with a Viton face seal ensure reliable boost holding even up to 50psi.

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

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.

GFB Warranty

Built-in Obsolescence? Not with GFB!

We live in a throw-away society, conditioned by cheap products and frequently released new models, to expect eventual failure and discard something when it stops working or is superseded. However, pride in workmanship and our commitment to quality means that when we put our name to something, we are also staking our reputation on it.

That’s why we back our products with the best Warranty in the business! You should expect a lifetime of use from a well-engineered product, so if your GFB product fails as a result of defective materials or faulty workmanship whilst you remain the original owner, we will repair or replace it. For full warranty details, please visit the GFB Australia website.

If the fault of occurred as a result of usage outside of the terms of the warranty, or you are not the original owner, fear not, we can still help you. You should never need to throw a GFB product away, as spare parts are available and won’t cost the earth.

Tech Support: We don't have a "Tech Support" team or department. We have engineers. When you contact us through our tech support email, you will be dealing directly with the engineers who actually design GFB products. They have more experience with the product than anyone on the planet to ensure you get the right advice.
