BMW M5 F90 and BMW M8 F92 F93 F91 Water Meth Upgrade - Proven charge cooling and octane headroom

If you are chasing lower intake temps, stronger knock resistance and consistent performance on UK pump petrol, this WMI setup has long been a favourite with our team and our customers. Matched to a popular piggyback tuner via CAN data, it delivers smooth, progressive fluid delivery with proper failsafes and robust hardware. We have run this system on our own cars and supported many M5 and M8 owners who wanted repeatable power on the road, strip and track day sessions.

Why add water meth on the S63 twin turbo V8

Significant charge temperature reduction for harder, repeatable pulls and reduced heat soak
Octane effect that mimics race fuel on regular petrol for safer ignition advance and more boost
Detonation control and extra tuning headroom on the S63 platform
Ideal companion for a piggyback controller with CAN integration and proper safety logic

Highlights - premium components and integration

Integrated control via FSB and CANbus data - mapping by boost, throttle, RPM, IAT, ignition and gear for precise delivery
Flow monitoring with failsafe - if flow drops or the tank runs dry, boost is reduced to protect the engine
Progressive strategy - power kept conservative until fluid is confirmed flowing to avoid tip-in knock
App visibility when paired with a compatible piggyback - enable or disable WMI, automatic disengage on safety events, log flow data
Aquatec pump, high speed solenoid, in-line filter and leak-free compression fittings for reliable operation
Choice of reservoirs - compact 1 gallon or boot mounted 2 gallon, or plumb into the washer bottle for an OEM-style install
F90 specific nozzle adapters with two BM7 injectors for a clean, reversible fit
