BMS BMW S63TU Water Injection Kit - BMW M5 and BMW M8 WMI Upgrade
Looking for a proven BMW M5 water injection kit or BMW M8 water methanol kit in the UK to unlock cooler intake temps, higher effective octane and safer power on pump fuel? The Burger Motorsports S63TU Water Methanol Injection Kit for the BMW F90 M5 and BMW F9x M8 has long been a favourite with UK enthusiasts and our own workshop team, delivering consistent results with JB4 integration, robust hardware and smart failsafes. Although this exact kit is discontinued, the information below remains a helpful reference. For current availability, choose the Snow Performance Stage 2 WMI as the ideal alternative for the BMW S63TU platform.
Why Water Methanol Injection on S63TU M5 and M8
- Lower intake air temperatures for harder, repeatable performance on road and track
- Race-fuel style octane effect on pump petrol - comparable to running 100 octane or E85 with additional charge cooling
- Improved knock resistance and safer tuning headroom on the BMW S63TU twin turbo V8
- Ideal for tuned F90 M5 and F9x M8 owners seeking reliable power gains with JB4
Key Features - BMS BMW M5 and M8 Water Methanol Injection Kit
- Seamless JB4 integration via FSB module and CANbus - precise mapping by boost, throttle, RPM, intake temp, ignition advance and gear
- Flow monitoring and failsafe - if the tank runs dry or flow drops, the JB4 reduces boost to protect the engine
- Smooth progressive delivery - boost held low until WMI is flowing to avoid tip-in knock common with non-integrated kits
- JB4 Mobile control - enable or disable WMI from the JB4 app, automatic disengage under traction control or safety map events, and log WMI flow data
- High quality Aquatec pump, high speed solenoid with leak-free compression fittings and in-line filter
- Choice of tank setups - 1 gallon clear tank or 2 gallon trunk mount, or integrate with the washer fluid reservoir
- F90 plug-and-play nozzle adapters with two BM7 nozzles for a clean, reversible install
