Description
The GFB DV+ T9386 Integrated Solenoid Diverter Valve is a high-performance replacement solution designed for modern BMW turbocharged engines equipped with newer-generation electronic OEM diverter valves. Developed specifically for BMW N13, N20, and N55 engines, the T9386 replaces the factory diverter valve assembly with a stronger, more reliable design that improves boost control, throttle response, and overall turbocharger performance.
Unlike earlier BMW diverter valves that could be modified with a DV+ upgrade kit, newer-generation OEM diverter valves are not serviceable and cannot be disassembled. GFB engineered the T9386 as a complete replacement diverter valve featuring an integrated low-profile solenoid, allowing for a direct-fit installation without clearance issues while maintaining factory ECU operation.
The GFB DV+ T9386 retains factory electronic control and recirculates vented air, providing a performance-focused upgrade without affecting drivability or requiring additional tuning.
Key Benefits
- Improved boost holding by eliminating common OEM diverter valve leakage issues
- Sharper throttle response with smoother boost control
- Faster boost recovery after gear changes or brief throttle lifts
- Stronger construction compared to factory plastic diverter valves
- Precision-machined components designed for long-term durability
- Direct-fit replacement retaining factory ECU control
- Backed by GFB’s lifetime warranty
Improved Boost Holding
Factory electronic diverter valves have undergone multiple revisions over the years to improve reliability, but their plastic construction and operating design can still create performance limitations. Many OEM diverter valves experience boost leakage, especially when mounted remotely on plastic charge piping rather than directly on the turbocharger.
The GFB DV+ T9386 addresses these issues with a precision-machined integrated piston seat built directly into the valve body. This design provides a reliable sealing surface and works effectively even when the factory plastic valve seat has imperfections.
The upgraded Viton face seal used on the DV+ piston further improves sealing performance, helping prevent boost loss and maintaining consistent turbocharger pressure.
Sharper Throttle Response and Faster Boost Recovery
Factory electronic diverter valves operate in a simple open-or-closed manner, while throttle inputs are constantly changing. This difference can create inconsistent power delivery during partial throttle adjustments.
The patented GFB DV+ pilot actuation system allows the piston to open and close progressively, improving airflow control and creating smoother throttle modulation. The result is improved throttle response, quicker boost recovery after gear shifts, and a more responsive driving experience.
Built for Long-Term Performance
The GFB DV+ T9386 is manufactured using high-quality materials and precision engineering to provide exceptional durability compared to factory diverter valves. Designed for enthusiasts who demand reliable turbo performance, the DV+ delivers consistent operation under demanding driving conditions and is backed by GFB’s lifetime warranty.
