Go Fast Bits DV+ Diverter Valve Upgrade for BMW N55 - T9356
Upgrade your BMW N55 turbocharged engine with the Go Fast Bits DV+ T9356 diverter valve. This is the proven fix for weak factory diverter valves that leak boost and slow throttle response. The GFB DV+ retains the fast factory solenoid control for lightning ECU response, then replaces the fragile plastic internals with hard-wearing anodised billet aluminium and a precision brass piston. The result is sharper throttle, stronger boost-holding, quicker actuation and rock-solid reliability. Perfect for BMW 135i, M135i, M235i, 335i and 435i owners who want a direct-fit, performance diverter valve upgrade that just works.
We run DV+ on our own N55 cars and we have fitted it for many Nforcd customers. Feedback is consistently the same - faster spool, cleaner shifts, improved part-throttle response and no flutter or surge. If you are searching for a BMW N55 diverter valve, N55 DV upgrade, BMW 135i diverter valve, M135i DV+, M235i DV+, F30 335i diverter valve, F32 435i diverter valve, GFB DV+ T9356, or BMW turbo recirculation valve upgrade in the UK, this is the one to buy.
Why choose the GFB DV+ T9356
- Retains factory solenoid coil for the quickest ECU-driven response
- Upgrades weak OE plastic parts to billet aluminium housing with a brass piston
- Exclusive pilot-actuated valve mechanism for ultra-fast response under high boost
- Holds more boost, improves throttle response, reduces lag, avoids compressor surge
- Direct-fit install - no rewiring and no extra vacuum lines required
- Designed for long-term reliability even on tuned cars
Many modern Euro cars use an electronically controlled diverter that reacts quickly, but the internal diaphragm or plastic piston is the weak link. The DV+ keeps what is good and upgrades what is not. No gimmicks, no compromises, just better performance and durability from a simple bolt-on.
