BMS 3 Gallon Stealth Water/Methanol Injection (WMI) Tank for F chassis BMW

3 Gallon Stealth Water/Methanol Injection (WMI) Tank for F Chassis BMW hides under the deck in your trunk! This tank is a completely custom design that neatly hides away in the trunk cavity below the deck lid found in 2013+ F3X and 2015+ F8X chassis vehicles.

The Water/Methanol Injection (WMI) pump mounts directly to the bottom of the tank allowing for a quick, clean, and completely stealthy installation. The bottom of the tank includes a sump and baffle, 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.
