Fuel Injector Clinic 1440cc High-Z Fuel Injector Set (ish01-1440h) - Holley GM and Ford
Give your high-performance Holley GM or Ford fuel system the flow capacity and precise fuel control it needs with the Fuel Injector Clinic 1440cc High-Z Fuel Injector Set. Part number ish01-1440h includes eight saturated, high-impedance injectors rated at 1440cc/min (140 lbs/hr) at 43.5 PSI and approximately 1700cc/min (160 lbs/hr) at OE 58 PSI fuel pressure. Excellent linearity and repeatable short pulse width operation help deliver the predictable fueling tuners need for strong drivability while providing substantial fuel capacity for serious performance combinations.
Fuel Injector Clinic precisely flow matches each injector set to within 1%. Every injector is individually numbered, and its results are documented on the detailed flow sheet supplied with the set. FIC flow tests and rates its high-performance injectors at 43.5 PSI (3 Bar) and 90 degrees F fuel temperature using CF-16B calibration fluid. Superior short pulse width control and tight manufacturing tolerances make the ish01-1440h easier to tune while maintaining consistent fuel delivery throughout the operating range.

Injector Plug and Wiring Options
The ish01-1440h is available with multiple connection options for different wiring harness configurations. PGTUSC8 solder-in pigtails can be used to replace the existing injector connectors. FIC also offers a direct EV6 connection option, a PADPUtoJ8 plug-and-play adaptor for EV1 connections, and a PADPUtoGM8 plug-and-play adaptor for Multec II connections. The adaptor options allow the appropriate connection to be made without cutting or soldering the vehicle harness.
Fuel Injector Clinic supplies brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors. For aftermarket fuel systems, custom installations, or other non-standard setups, contact Beefcake Racing before ordering to confirm the correct injector and connector configuration for your combination.
