Fuel Injector Clinic 775cc High-Z Fuel Injector Set (IS155-0775H) - Dodge 5.2L / 5.9L / 4.7L / 6.4L
Upgrade your Dodge fuel system with the Fuel Injector Clinic 775cc High-Z Fuel Injector Set, engineered for select 5.2L, 5.9L, 4.7L, and 6.4L applications. The IS155-0775H includes eight saturated, high-impedance injectors rated at 775cc/min, or 74 lbs/hr, at 43.5 psi (3 Bar). At the Dodge OE fuel pressure of 58 psi (4 Bar), these injectors flow 900cc/min, or 85 lbs/hr. Excellent linearity and short pulse width repeatability provide the precise, predictable injector response needed for accurate tuning and strong drivability while delivering the increased fuel capacity demanded by higher-output combinations.
Fuel Injector Clinic precisely matches each IS155-0775H set using its proprietary Data Match Technology. Every injector is individually serial numbered, with detailed flow matching and latency results supplied on the included Data Match Sheet. FIC flow tests and rates these injectors at 43.5 psi (3 Bar) and 90 degrees F fuel temperature using calibration fluid. Designed as a drop-in upgrade for both physical size and electrical plug in the listed factory applications, the IS155-0775H requires no injector connector conversion. Plug-and-play Dodge ECU data is also available from Fuel Injector Clinic.

775cc Rated Flow and 85 lbs/hr at OE Fuel Pressure
Injector flow changes with fuel pressure, making both ratings important when planning your Dodge fuel system. Fuel Injector Clinic rates the IS155-0775H at 775cc/min, or 74 lbs/hr, at its standard 43.5 psi (3 Bar) test pressure. At the Dodge OE fuel pressure of 58 psi (4 Bar), the same injector flows 900cc/min, or 85 lbs/hr. Understanding both figures gives you and your tuner a clearer picture of available injector capacity at the fuel pressure used by the vehicle.
Data Match Technology for Consistent Fuel Delivery
More injector capacity only helps when all eight injectors deliver fuel consistently and predictably. Fuel Injector Clinic precisely matches each IS155-0775H set using its proprietary Data Match Technology. Every injector is individually serial numbered, and the included Data Match Sheet provides detailed flow matching and latency information. That gives your tuner valuable injector-specific data for accurate ECU calibration and consistent fuel delivery across all eight cylinders.
Short Pulse Width Control and Drivability
A performance injector needs to work accurately across the entire operating range, not just when the engine is demanding maximum fuel. The IS155-0775H combines excellent linearity with strong short pulse width repeatability and state-of-the-art matching, helping the ECU precisely control smaller quantities of fuel during idle, cruising, and part-throttle operation. The result is increased fuel capacity without overlooking the tunability and drivability that matter in a street-driven performance Dodge.
Drop-In Size and Plug Installation
The IS155-0775H is designed as a drop-in upgrade for both physical size and electrical plug in the listed factory applications. No injector connector conversion is required, eliminating the need for solder-in pigtails or electrical adapters. Fuel Injector Clinic also supplies the O-rings required for the factory applications. If your Dodge uses an aftermarket fuel rail or another non-standard fuel system configuration, injector fitment should be confirmed before ordering.

FAQs
Why are the FIC IS155-0775H injectors rated at both 775cc and 900cc?
Both ratings are correct because injector flow changes with fuel pressure. Fuel Injector Clinic rates the IS155-0775H at 775cc/min, or 74 lbs/hr, at 43.5 psi (3 Bar). At the Dodge OE fuel pressure of 58 psi (4 Bar), the injectors flow 900cc/min, or 85 lbs/hr.
Do the FIC IS155-0775H injectors require a connector conversion?
No. Fuel Injector Clinic specifies the IS155-0775H as drop-in for both size and plug in the listed factory applications, so no injector connector conversion is required.
