Fuel Injector Clinic 540cc High-Z Fuel Injector Set (ish03-0540h) - Holley GM Composite Intake
Upgrade the fuel system on your Holley GM composite intake with the precision and consistency of the Fuel Injector Clinic 540cc High-Z Fuel Injector Set. Part number ish03-0540h includes eight saturated, high-impedance injectors flowing 540cc/min, or 52 lbs/hr, at 43.5 PSI fuel pressure and 60 lbs/hr, or 625cc/min, at the OE 58 PSI fuel pressure. Built with modern injector technology, this set delivers excellent linearity and short pulse width repeatability for accurate fueling across a wide operating range.
Fuel Injector Clinic precisely flow matches each ish03-0540h injector set to within 1 percent. Every injector is individually numbered, with the results for each injector documented on the detailed flow sheet supplied with the set. Combined with tight manufacturing tolerances and superior short pulse width control, that consistency gives your tuner a solid foundation for dialing in fueling while helping maintain the drivability you expect on the street. Plug-and-play GM ECU data is also available from Fuel Injector Clinic to further support accurate calibration.

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 you are using aftermarket fuel rails, a modified intake, or another unusual fuel system configuration, contact Beefcake Racing before ordering to verify proper injector fitment.
FAQs
What is the flow rate of the Fuel Injector Clinic ish03-0540h injector set?
These injectors are rated at 540cc/min, or 52 lbs/hr, at 43.5 PSI (3 Bar) fuel pressure. At the OE 58 PSI (4 Bar) fuel pressure, they are rated at 60 lbs/hr, or 625cc/min.
Why does precise injector flow matching matter?
Fuel Injector Clinic matches the injectors in each ish03-0540h set to within 1 percent and supplies a detailed flow sheet with the individual injector results. Consistent injector-to-injector fuel delivery gives the ECU and tuner a more predictable foundation for calibration, while superior short pulse width control helps promote smooth drivability at lower fuel demands.
Why Buy Fuel Injector Clinic Injectors From Beefcake Racing?
Getting the right injectors means more than choosing a flow number. Injector configuration, fuel pressure, intake design, fuel rails, and the rest of the fuel system all need to work together. Beefcake Racing can help you determine whether the Fuel Injector Clinic ish03-0540h set is the right match for your Holley GM composite intake and performance combination.
