Fuel Injector Clinic 1440cc Fuel Injector Set - High Z (is186-1440h) - 2003-2009 Nissan 350Z / 2009-2021 Nissan 370Z
Give your Nissan 350Z or 370Z the fuel capacity to support a serious performance build with the Fuel Injector Clinic 1440cc High-Z Fuel Injector Set. Positioned between FIC's 1200cc and 1650cc offerings, this set includes six 1440cc saturated, high impedance ball and seat injectors that combine substantial fuel delivery with excellent idle performance and precise low-pulse-width control. Whether your build runs gasoline, E85, or race fuel, the is186-1440h provides the flow capability higher-horsepower combinations demand while retaining the tunability and drivability that matter on a street-driven performance car.
Fuel Injector Clinic's 1440cc injector uses stainless alloy valve construction for 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 FIC'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. PGTUSC6 solder-in pigtails and the O-rings required for the listed application are included, while optional PADPUtoD6 plug-and-play adapters provide a wiring solution without cutting or soldering the factory harness. Every injector is covered against failure caused by defects in original manufacture by Fuel Injector Clinic's lifetime warranty.
