Overview
The Fuel Injector Clinic 1650cc high impedance injector set is designed for 2007-2013 Chevrolet and GMC trucks and SUVs equipped with 4.8L, 5.3L, or 6.0L Vortec V8 engines. Utilizing high impedance Bosch core injectors, this set features drop-in fitment with factory-style connectors and includes fuel rail spacers where needed. Each injector is individually serial numbered and flow matched using proprietary Data Match Technology, with complete flow and latency values provided on the included Data Match Sheet.
Built with stainless alloy valve construction, these injectors are fully compatible with pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. They offer short pulse width control for street drivability and idle performance while supporting higher output. FIC provides plug-and-play GM ECU data, and Max Redline can tune the car for the new injectors through log-based remote tuning or in-shop service. Tuning is required after installing larger injectors. Free shipping is included.
