GFB - Go Fast Bits T9358 DV+ Performance Diverter Valve Blow Off Valve

The GFB DV+ diverter valve (also called a blow off valve or BOV) is a direct replacement for a factory-fitted solenoid-type diverter valve. It keeps the factory ECU control and recirculates the vented air, making it a purely performance-oriented upgrade with no extra plumbing.

Key Features:

• Direct-fit replacement that uses the existing factory solenoid coil
• Replaces the valve mechanism with an anodised billet aluminium housing fitted with a brass piston machined to exacting tolerances
• Metal replaces plastic valve parts for reliability and strength on chipped engines
• Exclusive pilot-actuated valve mechanism for rapid response at high boost
• Includes GFB's TMS benefits
• Works with stock hardware

Benefits:

• Sharper throttle response
• Faster boost recovery on gearshift
• Solves boost leaking issues
• Able to hold higher boost pressure

The factory solenoid is quick because the ECU opens it faster than any pneumatic valve, so the DV+ keeps it and replaces only the weak point, the valve mechanism itself. Unlike systems that replace the entire setup with a traditional pneumatic valve, it avoids long vacuum hose runs, intake manifold vacuum taps, and a different solenoid or ballast resistor in the wiring loom, so installation is simpler. Recirculating the vented air means no noise and no nonsense, just performance.
