GFB T9354 DV+ Performance Diverter Valve for Ford Volvo Porsche Borg Warner Turbos

The GFB T9354 DV+ is a fully recirculating direct factory replacement for the pneumatic diaphragm type bypass valve (BPV) used on Ford, Volvo, Porsche, and Borg Warner turbocharged engines. Designed for enthusiasts who want performance without noise, this upgraded diverter valve solves the common failures associated with weak factory plastic components.

Key Performance Benefits:

• Up to 30% faster boost recovery on gearshift using GFB's TMS (Turbosmart Management System) technology
• 10% faster opening and 50% faster closing compared to factory diverter valves
• Pilot actuated operation for increased throttle response and drivability, replacing weak plastic components with metal construction to solve boost leaks
• Capable of handling upwards of 50psi boost pressure
• Progressive valve opening with adjustable spring preload for sharper throttle response

Superior Construction:

• Proven metal and silicone construction of valve components for lifetime durability in harsh conditions
• Anodized billet aluminum housing with precision-machined brass piston
• Retains factory solenoid and ECU control for simple installation and reliable operation
• Fully recirculating design maintains factory emissions compliance

What's Included:

• Valve body, retainer screw with washer, spring retainer, spring, vacuum nipple with O-ring, spring preload adjustment screw with O-ring, and piston

The DV+ design addresses factory valve shortcomings by replacing only what fails while keeping the working factory solenoid, making it a cost-effective and performance-oriented upgrade. Unlike factory bypass valves that cannot open and close progressively in response to boost pressure, the T9354 optimizes valve operation for both stock and modified engines, delivering noticeable improvements during throttle modulation and cornering.
