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, depending on injector choice 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.
