Fuel Injector Clinic 650cc High-Z Fuel Injector Set (is111-0650h) - 1990-2005 Honda/Acura NSX
Step up the fueling capability of your 1990-2005 Honda/Acura NSX with the Fuel Injector Clinic 650cc High-Z Fuel Injector Set. Part number is111-0650h includes six 650cc/min saturated, high-impedance ball-and-seat injectors engineered for excellent linearity, short pulse width repeatability, and consistent fuel delivery. With considerably more flow capacity for performance-oriented NSX builds while retaining the precise low-pulse-width control needed for drivability, this matched injector set gives tuners a strong foundation for accurate calibration across the engine's operating range.
Fuel Injector Clinic precisely flow matches each is111-0650h injector set to within 1 percent. Every injector is individually numbered, and its results are documented on the detailed flow sheet supplied with the set. FIC flow tests and rates these high-performance injectors at 43.5 PSI (3 Bar) using CF-16B calibration fluid maintained at 90 degrees F. Tight manufacturing tolerances and superior short pulse width control help deliver consistent fueling across all six cylinders while making the injectors easier to tune for excellent drivability.
