GFB DV+ Diverter Valve w/Integrated Solenoid - Mercedes-AMG
GFB (Go Fast Bits) has built its name on solving the weak points of factory turbo hardware, and the DV+ range is the result. Designed as a direct fit performance upgrade, the DV+ retains factory ECU control while fixing the boost leaks and sluggish response that plague the OEM valve on the Mercedes-AMG platform.
This listing covers the T9388, developed specifically for late model Mercedes-AMG vehicles fitted with the AMG-branded or Pierburg factory diverter valve. Unlike earlier Pierburg valves, the newer AMG units can't be disassembled and rebuilt, so GFB engineered the T9388 with a low profile integrated solenoid as a complete drop-in replacement, avoiding the clearance issues that come with piecemeal solutions.
Key Features
- Complete replacement for OEM AMG and Pierburg diverter valves
- Integrated low profile solenoid for hassle free installation
- Retains factory ECU control and recirculating operation
- Improved boost holding and sharper throttle response
- Faster boost recovery after gearshifts or brief throttle lifts
- Backed by GFB's Lifetime Warranty
Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please confirm your Mercedes-AMG model and year before ordering.
