The GFB VTA valve is an atmosphere-venting blow-off valve engineered for specific turbo applications that retain the factory solenoid and ECU control on cars with electronic diverter valves. It replaces weak factory internals to improve strength and reliability, offers the signature vent-to-atmosphere blow-off sound and is tuned to deliver faster boost recovery, improved boost holding and sharper throttle response.
