Support massive power gains on your modern LS engine with our 1050cc SouthBay Fuel Injectors. These injectors are specifically calibrated for the short-style architecture found in the LS3, LS7, and various L-series engines. Whether you are building a high-boost supercharged setup or a high-compression E85 street machine, these injectors provide the flow headroom and precision atomization required for maximum performance.
Every set is rigorously flow-matched both statically and dynamically to within 1% of each other. This ensures that every cylinder receives identical fueling, preventing dangerous lean conditions and allowing your tuner to extract every bit of safe horsepower. Despite their high flow capacity, these injectors maintain excellent low-pulse-width control, resulting in a crisp idle and "stock-like" drivability that makes them perfect for high-performance street and track builds alike.
