Hawks Motorsports offers our clients this FICLS36 LS Series 36 lb/hr @ 4 Bar Fuel Injectors for LS1/LS6 - Set of 8 - Bosch 0280155759 - Fuel Injector Connection designed for enthusiasts upgrading or replacing the factory fuel injectors in GM LS-powered applications. These genuine Bosch injectors are professionally flow matched and balanced by Fuel Injector Connection (FIC) to provide consistent fuel delivery, improved reliability, and excellent drivability in naturally aspirated and mild performance combinations.

Rated at 36 lb/hr at 4 Bar (58 psi), these injectors are designed to operate with factory LS1-style returnless fuel systems while maintaining factory injector characterization data. Because they utilize the same injector data as the original LS1 injectors, little to no PCM calibration changes are typically required when replacing stock injectors with this matched set in compatible applications.

Each injector is cleaned, tested, and flow matched to ensure balanced fuel delivery across all eight cylinders. This helps improve idle quality, throttle response, and engine performance while maintaining OEM-style fitment.

These injectors are an excellent choice for stock replacement engines, mild camshaft upgrades, intake and exhaust modifications, or naturally aspirated performance builds requiring increased fuel capacity over factory injectors.
