Fuel Injector Clinic 1200cc High-Z Fuel Injector Set (ish03-1200h) - Holley GM Composite Intake
Give your Holley GM composite intake the fuel capacity and precise injector control required for a serious performance combination with the Fuel Injector Clinic 1200cc High-Z Fuel Injector Set. Part number ish03-1200h includes eight saturated, high-impedance injectors rated at 1200cc/min, or 110 lbs/hr, at 43.5 PSI and 130 lbs/hr, or 1350cc/min, at the OE 58 PSI fuel pressure. Previously offered as ish03-1100h, this injector set combines substantial fuel delivery with excellent short pulse width control, helping deliver the accurate fueling and drivability needed from idle and part throttle through high-load operation.
Every ish03-1200h set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Each injector is individually serial numbered, and the results are supplied on a Data Match Sheet with detailed flow-matching and latency information for accurate calibration. FIC flow tests and rates these injectors at 43.5 PSI using CF-16B calibration fluid maintained at 90 degrees F. Plug-and-play GM ECU data is also available from Fuel Injector Clinic, giving tuners proven injector data to work with when dialing in the combination.

Fitment
Designed for Holley GM composite intake applications. Fitment is based on the intake, fuel rail, wiring, and fuel system configuration rather than a specific vehicle year, make, or model. If your combination uses aftermarket fuel rails, a modified intake, or another unusual configuration, contact Beefcake Racing before ordering to verify proper injector fitment and connector requirements.
FAQs
What is the flow rate of the Fuel Injector Clinic ish03-1200h injector set?
The ish03-1200h injectors are rated at 1200cc/min, or 110 lbs/hr, at 43.5 PSI (3 Bar) fuel pressure. At the OE 58 PSI (4 Bar) fuel pressure, they are rated at 130 lbs/hr, or 1350cc/min. This injector set was previously offered as ish03-1100h.
Do the ish03-1200h injectors require an injector plug change?
Yes. This injector set requires the appropriate connector conversion for the vehicle wiring harness. Solder-in pigtails can be used to replace the existing injector plugs, or optional plug-and-play adaptors can provide the required connection without cutting or soldering. FIC uses this configuration so it can supply brand-new, unused performance injectors rather than relying on remanufactured or core-program injectors.
Why Buy Fuel Injector Clinic Injectors From Beefcake Racing?
Choosing the right injector requires more than simply picking a flow rate. The injector configuration, fuel pressure, intake, fuel rails, electrical connections, and tuning requirements all need to work together. Beefcake Racing can help you determine whether the Fuel Injector Clinic ish03-1200h is the right match for your Holley GM composite intake and performance goals.
