Unlock race-fuel style performance from your Gen 2 BMW G20 or G22 with the JB4 Water/Methanol Injection Kit. This complete Burger Motorsports WMI package integrates seamlessly with your JB4, adding effective octane and robust charge air cooling to help your B48 or B58 engine deliver stronger, safer power on pump fuel. Available from Nforcd, it is a proven upgrade for drivers seeking a high quality water methanol injection system that works hand in hand with JB4 mapping and safety features.
- JB4-integrated WMI control for precise, progressive delivery using CANbus data such as boost, throttle, RPM, IAT, gear and more
- Built-in failsafes via JB4: reduces performance if flow drops or the tank runs dry and holds boost low until WMI is flowing
- Race-fuel or E85-like effect with additional charge cooling for improved performance on standard pump petrol
- Stealth 3.5 gallon boot tank tucks neatly into the left-side cavity on most G20 and G22 models for a clean OEM-like install
- High quality Aquatec pump, high speed solenoid and leak-free compression fittings for reliable operation
- Control and monitoring through the JB4 Mobile app, with WMI activation, deactivation and logging visibility
The kit includes the 3.5 gallon integrated stealth tank with rear sump, FSB JB4 Water/Methanol Injection Controller, Aquatec WMI pump, BMS BM10 super-atomising nozzle, high speed solenoid, steel braided lines with AN fittings, inline filter, wiring, brackets and mounting hardware. An optional upgraded blue billet tank cap with 1-way check valve is available separately.
Nozzle specification: supplied with a BM10 nozzle rated at 10 GPH (approximately 750 ml per minute), suitable for most B58 applications. Installation requires an 1/8 inch NPT port or the throttle plate adapter.
Optional plug and play Gen 2 B58 throttle body adapter: CNC machined with integrated O-ring, this adapter fits between the throttle body and intake manifold so you can mount two meth nozzles without changing the factory charge pipe. Simply remove three bolts, insert the adapter and refit with the supplied longer bolts for a secure, sealed install.
