Why enthusiasts choose a water methanol injection kit
Water methanol injection, also known as WMI, water meth injection or a meth kit, is a game-changing upgrade for turbocharged BMW and Audi engines. A quality BMW water methanol injection kit dramatically reduces intake air temperatures and effectively raises octane, helping support more boost and timing on pump fuel for stronger, safer performance. Think consistent, repeatable power and improved knock resistance on the road and at the track.
Engine coverage and popular searches
Optimised for the platforms enthusiasts search for every day: BMW N20, N26, N54, N55, B48, B58, S55 and S63. Perfect for owners searching BMW N54 water meth kit, BMW N55 WMI kit, BMW B58 meth kit, BMW S55 M3 M4 water methanol injection, BMW S63 M5 M6 meth injection and universal Audi water methanol injection kits.
Proven hardware with smart integration
This Burger Motorsports WMI solution integrates with the JB4 tuning system for precise progressive control based on boost, throttle position, RPM, intake temperature, ignition advance, gear and other CANbus data. The pump flow signal feeds back to the JB4 so if the tank runs dry or flow drops, power is safely reduced to avoid knock. You can enable or disable WMI from the driver’s seat, it disengages automatically with traction control or safety maps, and flow data can be viewed on the dash and via JB4 Mobile logging.
Hardware highlights include a high quality 220 psi Aquatec pump, a methanol-compatible solenoid with filter, robust compression fittings to help prevent leaks, and comprehensive wiring and mounting hardware. Super atomising 1/8 NPT nozzles from CoolingMist deliver excellent atomisation and flow, improving distribution and consistency.
