Fuel Injector Clinic 650cc Fuel Injector Set - High Z (is186-0650h) - 2003-2009 Nissan 350Z / 2009-2021 Nissan 370Z
Upgrade the fuel system in your Nissan 350Z or 370Z with the Fuel Injector Clinic 650cc High-Z Fuel Injector Set. Designed for VQ35 and VQ37 applications using the top-feed injector configuration, this set includes six 650cc saturated, high impedance ball and seat injectors built to deliver increased fuel capacity while maintaining the precise control needed for excellent drivability. Great linearity and short pulse width repeatability make these injectors a strong choice for modified VQ-powered street and performance builds where consistent, predictable fuel delivery is critical to a quality tune.
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. Fuel Injector Clinic flow tests and rates these injectors at 43.5 PSI (3 Bar) with fuel at 90 degrees F using CF-16B calibration fluid. The injectors include the O-rings required for the listed application along with PGTUSC6 solder-in pigtails. Optional PADPUtoD6 plug-and-play adapters provide an installation option without cutting or soldering the factory harness. Fuel Injector Clinic uses brand-new, unused injectors for its performance applications, and every injector is covered against failure caused by defects in original manufacture by its lifetime warranty.
