Fuel Injector Clinic 525cc High-Z Fuel Injector Set (IS155-0525H) - Dodge 5.2L / 5.9L / 4.7L / 6.4L
Upgrade your Dodge fuel system with the Fuel Injector Clinic 525cc High-Z Fuel Injector Set, designed for select 5.2L, 5.9L, 4.7L, and 6.4L applications. The IS155-0525H includes eight saturated, high-impedance injectors rated at 525cc/min, or 50 lbs/hr, at 43.5 psi (3 Bar). At the Dodge OE fuel pressure of 58 psi (4 Bar), these injectors flow 600cc/min, or 58 lbs/hr. Excellent linearity, short pulse width control, and tight manufacturing tolerances help deliver the predictable fueling needed for accurate tuning while maintaining excellent drivability.
Fuel Injector Clinic precisely flow matches each IS155-0525H injector set to within 1%. Every injector is individually numbered, with the results for each injector documented on the detailed flow sheet included with the set. FIC flow tests and rates these injectors at 43.5 psi (3 Bar) and 90 degrees F fuel temperature using CF-16B calibration fluid. Designed as a drop-in upgrade for both physical size and electrical plug in the listed factory applications, the IS155-0525H eliminates the need for an injector connector conversion. Plug-and-play Dodge ECU data is also available from Fuel Injector Clinic.

525cc Rated Flow and 58 lbs/hr at OE Fuel Pressure
Injector flow changes with fuel pressure, so understanding both ratings is important when selecting injectors for your Dodge. Fuel Injector Clinic rates the IS155-0525H at 525cc/min, or 50 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 600cc/min, or 58 lbs/hr. That OE-pressure rating gives you and your tuner a more useful picture of the injector's available fuel delivery in the vehicle.
Precisely Flow Matched to Within 1%
Consistent fuel delivery across all eight cylinders is critical to a properly calibrated performance engine. Fuel Injector Clinic precisely flow matches the injectors in each IS155-0525H set to within 1%. Each injector is individually numbered, and its results are listed on the detailed flow sheet included with the set. This level of matching provides consistent injector performance across the engine and gives your tuner dependable information to work with during calibration.
Short Pulse Width Control and Street Drivability
Performance injectors need to operate accurately across the entire RPM and load range, not just when the engine is demanding maximum fuel. The IS155-0525H combines excellent linearity, superior short pulse width control, and tight manufacturing tolerances to provide predictable injector response during idle, cruising, part-throttle operation, and higher-load conditions. That combination helps make these injectors easy to tune while maintaining the drivability expected from a street-driven Dodge.
Drop-In Size and Plug Installation
The IS155-0525H 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 plug 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 IS155-0525H injectors rated at both 525cc and 600cc?
Both ratings are correct because injector flow changes with fuel pressure. Fuel Injector Clinic rates the IS155-0525H at 525cc/min, or 50 lbs/hr, at 43.5 psi (3 Bar). At the Dodge OE fuel pressure of 58 psi (4 Bar), the injectors flow 600cc/min, or 58 lbs/hr.
Do the FIC IS155-0525H injectors require a connector conversion?
No. Fuel Injector Clinic specifies the IS155-0525H as drop-in for both size and plug in the listed factory applications, so no injector connector conversion is required.
