NOTE: ONLY INSTALL IF CAR IS BEING TUNED. DUE TO THE OEM ECU SOLENOID CONTROL STRATEGY COMBINED WITH THE VTA DESIGN THE VALVE CAN BE OPENED IN CERTAIN CONDITIONS WHICH CAN HAVE THE CAR STUMBLE AND STALL
If you want aggressive sound without sacrificing performance, the GFB T9483 VTA delivers both. Designed specifically for the FA24-powered Subaru WRX VB and VN platforms, this vent-to-atmosphere blow-off valve combines the unmistakable blow-off sound enthusiasts love with genuine performance improvements over the factory diverter valve.
By merging atmosphere venting with the proven internals of GFB’s DV+ technology, the VTA improves throttle response, holds boost more reliably, and delivers faster boost recovery between shifts. Installation is straightforward thanks to the compact, low-profile design with an integrated solenoid—simply remove the factory diverter valve and bolt the VTA in its place.
Unlike spacer-style solutions that only redirect air for noise, the VTA replaces the OEM diverter valve entirely, addressing its known sealing and response limitations. The result is not just better sound, but improved drivability, reliability, and turbo efficiency.
Reliable boost control:
Factory electronic diverter valves rely on moulded plastic components that struggle to seal consistently under boost. The VTA replaces these with CNC-machined aluminium and brass internals paired with a durable Viton piston seal. Boost pressure actively forces the valve shut, allowing the VTA to hold boost levels up to 50 psi without leaking or blowing open.
Sharper response and faster boost recovery:
OEM diverter valves operate in a simple on/off manner, which can cause abrupt power changes during throttle modulation. GFB’s patented pilot-actuated design allows the VTA piston to open and close progressively, venting only the air required to prevent compressor surge. This preserves boost in the intercooler longer, helping the turbo return to target boost more quickly when you get back on the throttle.
Built for longevity:
Precision manufacturing, robust materials, and a proven design ensure long-term reliability under demanding conditions. The VTA is engineered to last the life of the vehicle, which is why it is supported by GFB’s lifetime warranty.
