Increase the power of your vehicle by utilizing a water/meth injection kit. The purpose of water/meth injection is to reduce combustion temperatures and allow you to run higher boost pressures on pump gas. When using meth injection, pump gas will resist detonation much better because the methanol essentially raises the octane rating of the fuel and will allow you to run much more aggressive street tuning. This AEM kit has more features and components than any other comparably priced injection kits on the market. 1 Gallon tank with built in low level switch Boost referenced progressive controller ?Boost Safe? readiness safety system Check valve integrated into nozzle to prevent unintended fluid flow One injector and two nozzles to cover a wide range of HP levels High Pressure 200psi Recirculation-style pump Progressive Controller: Start Injection Boost 1-11psi.

Looking to make loads of power on pump gas? Enter: water/methanol injection. Regardless if you're tuned for conventional pump gas, E85, or race fuel, use of a properly configured and integrated water/meth system will reduce temperatures, allowing you to make more power than on just conventional fuel alone. Select your engine-specific nozzles (which are standard 1/8" NPT and install in most aftermarket chargepipes), your tank to mount in the trunk, upgraded steel braided lines if you so choose, and some boost juice and you just need a management solution! Optionally, add a BMS FSB for JB4 integration!

Make tremendous amounts of power on pump gas! Everything you need to get started with WMI in one convenient kit. JB4 compatible! Water/Methanol/Alcohol injection commonly referred to as WMI allows you to make tremendous amounts of power on pump gas. The effect is similar to running 100 octane race gas or E85 fuel all the time with the additional cooling benefits allowing for more power than you can make on race gas or E85 alone. For those that don't have easy E85 access WMI adds a on of power over pump gas, and for those running E85 WMI can still be very useful for its charge air cooling and fuel volume benefits. The key to a safe and effective WMI setup is tuning integration. The B58 BMS WMI kit integrates to the JB4 tuning system allowing for precise mapping based on boost, throttle position, engine speed, intake temperature, advance, gear, and other data elements available to the JB4 through its CANbus system. In addition, a pump flow signal is fed back to the JB4 allowing for a safe and smooth progressive boost mapping. If the tank runs empty or flow drops for any reason the JB4 will safely back down performance to avoid detonation. Boost is held low until WMI is properly flowing to avoid tip in knock common with non-integrated WMI setups. In addition WMI can be activated or disabled right from the JB4 Mobile app and will automatically disengage during traction control or safety map situations. WMI flow data can be displayed via your JB4 Mobile logging device. This water/methanol injection (WMI) tank is a completely custom design that neatly hides away in the left side trunk cavity found in most G20 G22 & G80 M3 & G82 M4 BMW vehicles. The pump mounts directly to the back of the tank allowing for a quick, clean, and completely stealth installation. The bottom of the tank includes a rear sump allowing for consistent performance even as the tank drains. Includes 2-way vented black plastic cap, a compression pump feed fitting, and 12" of vinyl WMI line for the non-pressure side of the WMI pump. This kit includes a BM10 (10 GPH or approx. 750 ml/min) injection nozzle suitable for most B58 applications. Mounting requires an 1/8" NPT port or the throttle plate adapter.

Normally you'd replace the factory charge pipe to install a water/methanol kit but in the case of the B58 engine, the factory charge pipe is very sturdy and difficult to remove. So we've designed this plug and play adapter for quick installation and removal of BMS dual nozzle water/meth kits without having to replace the factory charge pipe. Simply unscrew three bolts, insert the CNC machined adapter with integrated o-ring in place, and tighten the included longer length bolts, to allow mounting of two meth nozzles with a perfect seal. Includes dual 1/8" NPT methanol bungs appropriately machined for a clean spray pattern which is critical for proper atomization with the B58 motor. For most B58 water/methanol applications we suggest dual CM5 nozzles.

With CNC machined serviceable/cleanable nozzle inserts for precise fluid metering. Choose single or dual nozzles and match the flow rate to your power needs! Water/Methanol Injection (WMI) nozzles are determined by the intended power and how many bungs your charge pipe has. These nozzles are 1/8” NPT and screw in to bungs included on most aftermarket charge pipes. BMS "super atomizing" nozzles are designed and manufactured by BMS and are known for their great atomization and flow characteristics. The number on the methanol injection nozzle represents the approximate gallons per hour of fluid when at full flow. Generally speaking running two smaller nozzles is preferred to one larger nozzle for an equal flow to improve fluid atomization and distribution.
