GFB - Go Fast Bits T9357 DV+ Diverter Valve Blow Off Valve

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

Key Benefits:

• Sharper throttle response
• Faster boost recovery on gearshift
• Solves boost leaking issues
• Built to last

Key Features:

• Direct-fit replacement that works with stock hardware
• Retains the factory solenoid coil for seamless integration
• Replaces the weak valve parts with an anodised billet aluminium housing fitted with a brass piston machined to exacting tolerances
• Metal construction in place of plastic valve parts for reliability and strength on chipped engines
• Exclusive pilot-actuated valve mechanism for rapid valve actuation at high boost
• Direct-fit replacement with GFB's TMS benefits

The factory solenoid coil works well, since the ECU opens it faster than any pneumatic valve. The weak point is the valve mechanism itself, so the DV+ replaces just that part. Other approaches replace the entire system with a traditional pneumatic valve, which can need long vacuum hose runs, extra parts to tap into intake manifold vacuum, and either a different solenoid or a ballast resistor. The DV+ avoids those extra parts and is designed to install in less time.

The result is sharper throttle response, fast valve actuation, and the ability to hold higher boost pressure, with no noise and no nonsense.
