GFB T9465 VTA Blow Off Valve Diverter Valve Atmosphere Vent BOV

The GFB (Go Fast Bits) T9465 VTA is a blow off valve (BOV) and diverter valve upgrade. It is built for turbocharged engines with an electronic factory diverter valve. It gives you the signature turbo blow-off sound and better performance, including quicker boost recovery on gearshifts and sharper throttle response.

Key Features:

• Vents to atmosphere for the classic turbo blow-off sound
• TMS Technology for faster boost recovery on gearshift and during throttle modulation
• Improved boost holding ability
• Retains the factory solenoid and ECU control
• CNC machined billet components in place of the factory diverter's loose-fitting plastic valve
• Durable elastomer piston seal
• Direct bolt-on kit that includes what you need to install it

GFB's pilot-operation design reuses the factory solenoid to control the pressure behind the piston instead of the piston itself. This lets the piston open and close progressively as boost pressure changes. The result is smoother boost transitions and less of the lag caused by the factory diverter valve.
