Unlock serious performance on pump petrol with the Kia and Hyundai JB4 Water Methanol Injection Kit from Nforcd. This Burger Motorsports WMI upgrade increases effective octane and delivers charge cooling, enabling safer, stronger tuning on everyday fuel. Crucially, it integrates directly with your JB4 for precise, reliable control and built-in safety.
- Full JB4 integration via CANbus with mapping by boost, throttle position, RPM, intake temperature, ignition advance, gear and more
- Real-time pump flow feedback to the JB4 for smooth progressive control and automatic safety intervention if flow drops or the tank runs dry
- Boost is held low until WMI flow is established to help prevent tip-in knock found on non-integrated systems
- Control WMI from the JB4 Mobile app, with automatic disengagement during traction control or safety map events and WMI flow data available in logs
- High quality hardware including an Aquatec pump to BMS spec, high speed solenoid with leak-free compression fittings, WMI filter, wiring and all required mounting hardware
- Optional plug and play nozzle adapter for Kia Stinger, Genesis G70 and Hyundai Veloster N so you do not need to drill or weld the factory charge pipe
- Base kit contents: WMI pump, FSB controller for JB4, solenoid, filter, 20 feet of WMI line, compression fittings and wiring
