The FiTECH Ultimate LS 500 HP EFI System Long Runner is a comprehensive multi-port fuel injection solution purpose-built for GM LS-series engines. This sequential fuel injection system is designed to deliver precise metering across 36 lb/hr injectors and a 92mm aluminum throttle body, engineered to support up to 500 horsepower on naturally aspirated LS platforms.
The complete kit features a black powder-coated finish that resists corrosion in engine bay environments. It effectively handles the fuel delivery demands of high-performance street engines, track vehicles, and engine swap applications where reliable EFI control is essential. The 36 lb/hr injectors provide granular fuel control across idle, cruise, and full-load conditions, ensuring drivability in street applications.
This system is ideal for engine builders, performance technicians, and enthusiasts retrofitting LS engines into custom platforms or upgrading carbureted LS mills to modern fuel injection. The "Long Runner" designation indicates optimized intake manifold runner geometry for extended fuel column atomization and improved low-to-mid range performance.
