Fuel Injector Clinic 1650cc High-Z Fuel Injector Set (is111-1650h) - 1990-2005 Honda/Acura NSX
Give your high-horsepower NSX the fuel capacity it needs without giving up the control required for a street-driven performance car. The Fuel Injector Clinic is111-1650h includes six 1650cc/min saturated, high-impedance ball-and-seat injectors engineered for excellent linearity, short pulse width repeatability, and dependable drivability. With substantial fuel capacity for demanding gasoline and E85 combinations, these injectors are built for serious naturally aspirated, supercharged, and turbocharged NSX applications where accurate fuel delivery matters just as much as outright flow.
The 1650cc injector uses stainless alloy valve construction for broad fuel compatibility, including pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Fuel Injector Clinic precisely flow matches its high-performance injector sets to within 1 percent, individually numbers each injector, and provides documented results with the set. Injectors are flow tested and rated 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 make the is111-1650h easier to tune while maintaining the refined low-load operation expected from a properly calibrated NSX.
