T9388 DV+ T9388 Diverter Valve for Mercedes applications
supplied with integrated solenoid
The T9388 is the latest addition to the DV+ range of diverter valves from GFB (Go Fast Bits). It is designed as a complete drop-in replacement for the OEM diverter valve in late-model Mercedes vehicles.
Unlike the earlier generation diverter valves manufactured by Pierburg, the newer AMG-branded OEM valves cannot be disassembled and incorporated into a DV+. Therefore, GFB developed the T9388 with a low-profile integrated solenoid as a complete replacement for both the AMG and Pierburg diverter valves, enabling a hassle-free installation with no clearance issues.
Like all valves in the DV+ range, the new T9388 delivers the following benefits over the OEM diverter valve:
- Improved boost holding
- Sharper throttle response
- Faster boost recovery after a gearshift or brief throttle lift
- Unrivalled longevity, backed by our Lifetime Warranty
Fits the following Mercedes-Benz models:
