Fuel Injector Clinic 1650cc Fuel Injector Set for 240SX 11mm Setup - High Z (is181-1650h) - 1989-1998 Nissan 240SX S13 / S14
Feed a serious 1989-1998 Nissan 240SX build with the Fuel Injector Clinic 1650cc High-Z Fuel Injector Set for 11mm setups. Designed for S13 and S14 applications that demand substantial fuel delivery without giving up the control needed for street drivability, this set includes four 1650cc saturated, high impedance ball and seat injectors. Excellent idle performance, linearity, and short pulse width repeatability make the is181-1650h a strong choice for higher-horsepower 240SX combinations running gasoline, E85, or race fuel.
Stainless alloy valve construction gives the 1650cc injector broad fuel compatibility, including pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Each injector is individually serial numbered and precisely matched using Fuel Injector Clinic's proprietary Data Match Technology, with detailed flow matching and latency information supplied on the included Data Match Sheet. The injectors are flow tested and rated at 43.5 PSI (3 Bar) with fuel at 90 degrees F using CF-16B calibration fluid. Fuel Injector Clinic supplies the injectors with the O-rings required for the listed application, and PGTJETR4Q solder-in pigtails are included. Every injector is covered against failure caused by defects in original manufacture by Fuel Injector Clinic's lifetime warranty.
