Fuel Injector Clinic 445cc Fuel Injector Set - High Z (is186-0445h) - 2003-2009 Nissan 350Z / 2009-2021 Nissan 370Z
Upgrade the fuel system in your 2003-2009 Nissan 350Z or 2009-2021 Nissan 370Z with the Fuel Injector Clinic 445cc High-Z Fuel Injector Set. Designed for VQ35 and VQ37 applications using the top-feed injector configuration, this set includes six 445cc saturated, high impedance ball and seat injectors. Excellent linearity, short pulse width repeatability, and precise flow matching give tuners consistent, predictable fuel delivery while helping maintain the drivability that matters on a street-driven VQ-powered performance build.
Fuel Injector Clinic precisely flow matches each injector set to within 1 percent. Every injector is individually numbered, with detailed results supplied on the included flow sheet. FIC injectors are flow tested and rated at 43.5 PSI (3 Bar) with fuel at 90 degrees F using CF-16B calibration fluid. Superior short pulse width control and tight manufacturing tolerances help make these injectors easy to tune while providing excellent drivability. The set includes the O-rings required for the listed application and PGTUSC6 solder-in pigtails, while optional PADPUtoD6 plug-and-play adapters provide an installation option 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.
