Fuel Injector Clinic 1000cc High-Z Injector Set (ish01-1000h) - Holley GM and Ford
Upgrade your Holley-equipped GM or Ford fuel system with the Fuel Injector Clinic 1000cc High-Z injector set. This matched set of eight performance injectors is rated at 1000cc/min, or 95 lbs/hr, at 43.5 PSI fuel pressure, with the title-rated 100 lbs/hr at OE 58 PSI fuel pressure. Built for performance applications that demand increased fuel capacity without sacrificing low-speed control, these saturated high-impedance injectors deliver excellent linearity and short pulse width repeatability for predictable tuning and strong drivability.
Fuel Injector Clinic precisely flow matches the ish01-1000h injector set to within 1 percent. Each injector is individually numbered, and the results for every injector 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. The set includes PGTUSC8 solder-in pigtails, with optional PADPUtoJ8 plug-and-play adapters available for installations where cutting and soldering the vehicle harness is not desired.

1000cc High-Z Performance for Holley EFI Builds
The ish01-1000h gives Holley-equipped GM and Ford performance combinations significantly increased fuel capacity while maintaining the injector control needed for a properly calibrated engine. Strong linearity and short pulse width repeatability allow the ECU to accurately control fuel delivery across a broad operating range, making these injectors well suited to performance builds that still need predictable idle, cruising, and part-throttle behavior.
Precisely Flow Matched to Within 1 Percent
Consistent injector performance across all eight cylinders is critical to accurate fueling. Fuel Injector Clinic precisely flow matches the injectors in each ish01-1000h set to within 1 percent. Every injector is individually numbered, and its results are documented on the detailed flow sheet included with the set, providing valuable information for a properly configured performance fuel system.
Controlled Fuel Delivery and Drivability
Injector selection is about more than maximum flow capacity. At idle and light throttle, the ECU needs to accurately command extremely small amounts of fuel. The FIC 1000cc High-Z injector combines increased flow capability with superior short pulse width control and tight manufacturing tolerances, helping provide predictable tuning behavior and excellent drivability throughout the operating range.
Pigtails Included with Plug-and-Play Adapter Option
The ish01-1000h set includes PGTUSC8 pigtails for installations requiring an injector connector change. The supplied pigtails can be soldered into the vehicle wiring harness to replace the existing injector connectors. For installations where cutting or soldering the harness is not desired, optional PADPUtoJ8 plug-and-play adapters can be selected to provide the required connector conversion.
Fuel Injector Clinic chooses to supply brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors. Depending on the specific installation, this can make a connector conversion necessary, but it allows the injector set to be built around new components rather than previously used injector cores.
Fitment
- Holley GM applications
- Holley Ford applications
Fitment Note: This is a Holley GM and Ford application injector set rather than a vehicle-specific injector package. Injector fitment depends on the specific Holley intake, fuel rail, connector, and fuel-system configuration being used.
