1650cc BMW 2021-2024 M4/M3 G8X S58 Port Injectors

SouthBay Fuel Injectors feature high impedance Bosch cores that are compatible with all known fuels, including oxygenated varieties such as E85, MTBE, FTW, Q16, M5, and C45. They do not require a resistor box. The 1650cc SouthBay Fuel Injectors ensure precise fuel delivery and atomization for enhanced power and improved throttle response. They are dynamically flow matched to within ±1%, which, along with their fast response and linearity, results in exceptional idle qualities. Extensions, clips, and flow data are included. Designed for high-performance off-road applications, these injectors come with a lifetime warranty covering any defects from the original manufacturer.
