Ensure your LS swap has the fuel it needs with our 650cc SouthBay Fuel Injectors. Specifically curated for enthusiasts running the popular 5.3L LS engine in swapped applications, these injectors provide a significant step up from stock flow rates, making them ideal for engines with upgraded camshafts, intake manifolds, or entry-level turbo/supercharger kits.
These injectors are engineered to provide a linear flow rate and excellent atomization, which translates to a smooth idle and crisp throttle response—essential for maintaining the drivability of your swap. Each set is rigorously flow-matched within 1%, ensuring that your V8 runs balanced and stays protected against lean conditions under load. Built with stainless steel internal components, they are fully resistant to the corrosive properties of modern E85 and ethanol-blended fuels, offering long-term reliability for your project build.
