The VTA T9458 DV+ Performance Blow Off Valve stands as an impressive performance blow-off valve solution designed for those desiring both sound and enhanced performance will find that GFB's VTA provides an optimal solution. By combining the established performance advantages of the groundbreaking DV+ with atmosphere venting, the VTA offers a bold blow-off sound, along with improvements in throttle response, boost recovery, boost holding, and reliability, even under extreme conditions.
Following the same successful design philosophy as the DV+, the VTA adheres to the principle of "Keep what works, replace what doesn't." This entails the retention of ECU control and the factory solenoid to ensure the fastest possible response time, eliminating the added and unnecessary cost of solenoid replacement seen in some competitor brands.
Addressing the historical weak point of the factory diverter, which is the plastic valve mechanism, the VTA incorporates CNC machined billet components known for their longevity. Additionally, it introduces an improved valve operation method. Unlike the factory diverter valve, which operates in only two states (open or closed), the VTA capitalizes on GFB's innovative "pilot operation." This involves repurposing the factory solenoid to control the pressure behind the piston rather than directly actuating the piston itself. This innovative approach results in a shorter solenoid stroke, enhancing response time and increasing actuation force. Most importantly, it enables the piston to progressively open and close in response to varying boost pressure levels. This innovation leads to smoother boost transitions and a reduction in the lag commonly associated with the factory diverter valve.
This design philosophy positions the VTA as not only the best-performing blow-off valve solution but also the most cost-effective choice available on the market.

- Retains ECU control.
- Direct bolt-on kits include all necessary installation components.
- Manufactured in Australia in accordance with ISO 9001 standards.
Choosing Between VTA and DV+:
The choice between the VTA and DV+ primarily depends on the preference for sound. Both valves share the same quality materials and valve mechanism, offering equivalent performance and reliability benefits. However, the VTA provides an atmospheric venting option for those who desire sound, while the DV+ recirculates the air to maintain a quieter operation.
Why Opt for a VTA Over a BOV Spacer?
While BOV spacers are affordable and produce sound, their impact is limited to sound enhancement alone. They do not address the performance and reliability issues associated with the factory diverter valve. In contrast, the VTA significantly improves the operation of the diverter valve to offer both sound and performance enhancements.
Why Choose a VTA Over a Kit That Includes a Solenoid?
Opting for a VTA over a kit that includes a solenoid is recommended as there is no performance advantage in replacing the factory solenoid. Furthermore, such kits come at a significantly higher cost. The VTA, when equipped with the factory solenoid, can achieve extremely rapid actuation, eliminating the need for unnecessary expenses.
