GFB T9386 DV+ Integrated Solenoid Performance Diverter Valve for BMW N13, N20 & N55

The GFB T9386 DV+ Diverter Valve is the latest addition to Go Fast Bits' acclaimed DV+ performance diverter valve range, engineered as a complete, direct-fit replacement for the newer generation of OEM diverter valves found on BMW N13, N20, and N55 turbocharged engines.

Unlike earlier-generation factory diverter valves that could be partially disassembled and integrated into a DV+, the newer OEM units are sealed assemblies that cannot be modified. GFB addressed this by developing the T9386 with a low-profile integrated solenoid, making it a full drop-in replacement that installs without clearance issues or additional hardware.

Key Features:

• Integrated solenoid design — purpose-built for newer-generation BMW valves that cannot be disassembled
• Pilot-actuated valve mechanism — opens and closes progressively for smoother power delivery and sharper throttle response
• Improved boost holding — eliminates the significant boost leakage common in plastic OEM valve assemblies
• Faster boost recovery — reduces time to peak boost after gearshifts or brief throttle lifts
• Direct-fit replacement — installs with no modifications and no clearance concerns
• Metal valve construction — replaces weak plastic OEM components for superior durability under high boost and heat
• Retains factory ECU control — no tuning or recalibration required; recirculates vented air for OEM-style operation
• Lifetime Warranty — backed by GFB's industry-leading warranty
• ISO 9001 manufactured — produced in Australia to stringent quality standards

The T9386 utilizes GFB's proven TMS (Torque Management System) technology, which has been shown to return engines to peak boost up to 30% faster than a factory diverter valve during gear changes. The pressure-balancing piston design ensures the valve stays firmly closed under wide-open-throttle conditions regardless of boost level, eliminating the need for spring rate adjustments or frequent rebuilds.
