Fuel Injector Clinic 525cc High-Z Fuel Injector Set (IS156-0525H) - 2008-2013 Dodge 4.7L / 2003-Present 5.7L
Upgrade your Dodge 4.7L or 5.7L fuel system with the Fuel Injector Clinic IS156-0525H 525cc High-Z Fuel Injector Set. This complete set of eight saturated, high-impedance injectors flows 525cc/min, or 50 lbs/hr, at 43.5 psi (3 Bar) and 600cc/min, or 58 lbs/hr, at the Dodge OE fuel pressure of 58 psi (4 Bar). Designed for performance applications that need additional fuel capacity without giving up the control and drivability expected from a street-driven vehicle, these injectors combine excellent linearity, short pulse width control, and tight manufacturing tolerances for predictable fueling across the operating range.
Fuel Injector Clinic precisely flow matches each IS156-0525H injector set to within 1%. Every injector in the set is individually numbered, and its results are documented on the detailed flow sheet included with the injectors. FIC flow tests and rates its high-performance injectors at 43.5 psi (3 Bar) and 90 degrees F fuel temperature using calibration fluid. The IS156-0525H is also designed as a drop-in replacement for both physical size and electrical plug in the listed factory applications, eliminating the need for a connector conversion. Plug-and-play Dodge ECU data is available from Fuel Injector Clinic to further support proper calibration.

525cc Rated Flow and 58 lbs/hr at OE Fuel Pressure
Fuel Injector Clinic rates the IS156-0525H 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 injectors flow 600cc/min, or 58 lbs/hr. Because injector flow changes with fuel pressure, both figures are useful when planning a performance fuel system. The 58 psi rating provides a more application-relevant picture of the injector's available flow when operating at the specified Dodge OE fuel pressure.
Precisely Flow Matched to Within 1%
Fuel capacity alone does not determine the quality of a performance injector set. Consistency between injectors is critical to maintaining balanced fuel delivery across all eight cylinders. Fuel Injector Clinic precisely flow matches the IS156-0525H set to within 1%, individually numbers each injector, and supplies the corresponding results on a detailed flow sheet. This gives your tuner useful injector-specific information while helping maintain consistent fueling throughout the engine.
Short Pulse Width Control and Drivability
Performance injectors need to accurately meter fuel at idle and part throttle as well as under heavier engine loads. The IS156-0525H combines tight manufacturing tolerances with superior short pulse width control, helping provide predictable fuel delivery when the ECU commands small injector pulse widths. That control makes the injectors easier to tune while supporting the smooth idle, part-throttle response, and drivability expected from a properly calibrated street or performance Dodge.
Drop-In Size and Plug Installation
The IS156-0525H is designed as a drop-in upgrade for both physical size and electrical plug in the listed factory applications. No injector plug conversion is required, eliminating the need for solder-in pigtails or electrical adapters. Fuel Injector Clinic also supplies the O-rings required for the listed factory applications, and plug-and-play Dodge ECU data is available to assist with calibration. If your vehicle uses aftermarket fuel rails or another non-standard fuel system configuration, confirm injector fitment before ordering.

FAQs
Why are the FIC IS156-0525H injectors rated at both 525cc and 600cc?
Both figures describe the same injectors at different fuel pressures. Fuel Injector Clinic rates the IS156-0525H 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 IS156-0525H injectors require a plug or wiring conversion?
No. Fuel Injector Clinic specifies the IS156-0525H as drop-in for both size and plug in the listed factory applications. No injector connector conversion is required.
