Fuel Injector Clinic 1000cc High-Z Fuel Injector Set (ish03-1000h) - Holley GM Composite Intake
Give your Holley GM composite intake the fuel delivery and injector control needed for serious performance with the Fuel Injector Clinic 1000cc High-Z Fuel Injector Set. Part number ish03-1000h is an eight-injector set engineered around modern saturated, high-impedance injector technology and rated at 1000cc/min at 43.5 PSI, with a 110 lbs/hr rating at the OE 58 PSI fuel pressure. Whether the combination is naturally aspirated or built around forced induction, these injectors deliver the precise fuel control, consistency, and tunability demanded by a properly calibrated high-performance GM setup.
Fuel Injector Clinic goes beyond simply grouping eight injectors with the same advertised flow rate. The ish03-1000h set is precisely matched using FIC's proprietary Data Match Technology. Every injector is individually serial numbered, and the set includes a Data Match Sheet documenting injector-specific matching data. Superior short pulse width control and precise matching help the ECU accurately command fuel at low pulse widths, supporting easier calibration, smooth drivability, and consistent performance from idle through high-load operation. Plug-and-play GM ECU data is also available from Fuel Injector Clinic.

Fitment
Designed for Holley GM composite intake applications. Fitment is based on the intake and fuel system configuration rather than a specific vehicle year, make, or model. If your combination uses an aftermarket or unusual fuel system setup, contact Beefcake Racing before ordering to verify proper injector fitment.
FAQs
What makes Fuel Injector Clinic Data Match Technology important?
Data Match Technology precisely matches the injectors as a set and provides injector-specific information on the included Data Match Sheet. Accurate matching, combined with strong short pulse width control, gives the ECU more consistent fuel delivery to work with and can make a properly configured performance combination easier to tune while maintaining good drivability.
Will the ish03-1000h injectors fit every GM engine?
No. Part number ish03-1000h is specifically configured for Holley GM composite intake applications. Because aftermarket intake, fuel rail, and other fuel system combinations can change injector fitment requirements, contact Beefcake Racing before ordering if your setup differs from the intended configuration.
Why Buy Fuel Injector Clinic Injectors From Beefcake Racing?
When fuel delivery is a critical part of your build, getting the correct injector set matters just as much as choosing the right flow rate. Beefcake Racing can help you match Fuel Injector Clinic injectors to your performance goals and fuel system configuration so you can order with confidence.
