BMS 3.5 Gallon Stealth Water/Methanol Injection (WMI) Tank for G20 G22 & G80 M3 & G82 M4 BMW

Stealth Tank for G20 G22 & G80 M3 & G82 M4 BMW tucks neatly in the side pocket of your trunk! 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 and a compression pump feed fitting. The nozzles are determined by the intended power and how many bungs your charge pipe has.

The nozzles are 1/8” NPT and screw into bungs included on most aftermarket charge pipes. Our BMS "super atomizing" nozzles are well known for their great atomization and flow characteristics.

The nozzle number 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.

Below are some general nozzle suggestions but feel free to email us for nozzle advice if your situation is unique.
