Fuel Injector Clinic 525cc (58 lbs/hr at OE 58 PSI fuel pressure) FIC Fuel Injector Clinic Injector Set for 4.8/5.3/6.0 Truck Motors ( 99- 06) (High-Z)

Fuel Injector Clinic's high-performance fuel injector sets are precisely flow-matched to within 1%. Each injector is individually numbered with a detailed flow sheet included. They are flow tested and rated at 43.5psi (3Bar) at 90 degrees F fuel temperature using CF-16B calibration fluid. Superior short pulse width control and tight manufacturing tolerances make these injectors easy to tune and provide great drivability. They include all o-rings needed to fit the factory application. This set requires changing the injector plug on the wiring harness; pigtails are included, or optional plug-n-play adapters can be purchased. FIC uses new, unused injectors for its performance applications, not remanufactured. Covered by a lifetime warranty against manufacturing defects.
