T9489 is a direct bolt-on for Toyota GR Yaris and Corolla, and also fits other turbo Toyota/Lexus engines with an electronic OEM diverter valve.

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 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.
