S58 BMW G80 M3 & G82 M4 Water/Methanol Port Injection Kit

Make tremendous amounts of power on pump gas!

The Fuel-It! S58 BMW Port Injection Kit is the ultimate fueling solution for your S58 powered BMW.  It adds six supplemental low-pressure fuel injectors allowing fueling of up to 1000+ whp using water/methanol blends. 

This kit includes stainless steel BMS Elite braided lines. They feature an inner Teflon seal for leak-free operation, stainless steel braid, a black outer nylon mesh for abrasion resistance and a stealthy look. These lines not only look great they are also equipped with BMS Elite AN fittings and can withstand extreme pressure and temperature conditions. 

The included Burger Motorsports DDP 5800 water/methanol alcohol Injection pump is a heavy-duty pump used in all of our BMS Water Injection kits. 200 psi bypass for smooth and high pressure and 1.3 GPM open flow. Made in the USA. 

The Burger Motorsports JB4 Port Injection Controller attaches to the JB4 allowing it to directly control both traditional port injection kits and WMI port injection kits.

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.
