Fuel Injector Clinic 1200cc-D High-Z Fuel Injector Set (IS155-1200H-D) - Dodge 5.2L / 5.9L / 4.7L / 6.4L
Give your performance Dodge the fuel capacity and injector control needed for a serious power upgrade with the Fuel Injector Clinic 1200cc-D High-Z Fuel Injector Set. The IS155-1200H-D includes eight saturated, high-impedance injectors rated at 1200cc-D/min, or 110 lbs/hr, at 43.5 psi (3 Bar). At the Dodge OE fuel pressure of 58 psi (4 Bar), these injectors flow 1350cc/min, or 130 lbs/hr. Built around modern injector technology with excellent short pulse width control and precise matching, this set delivers the increased fuel capacity performance builds demand while maintaining the predictable response needed for accurate tuning and strong drivability.
Each IS155-1200H-D set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Every injector is individually serial numbered, with its results documented on the included Data Match Sheet to provide detailed flow matching and latency information for calibration. Fuel Injector Clinic flow tests and rates these injectors at 43.5 psi (3 Bar) and 90 degrees F fuel temperature using calibration fluid. The 1200cc-D is also an excellent option for E85 applications, and plug-and-play Dodge ECU data is available from Fuel Injector Clinic.

1200cc-D Rated Flow and 130 lbs/hr at OE Fuel Pressure
Injector flow changes with fuel pressure, making both ratings important when planning a performance Dodge fuel system. Fuel Injector Clinic rates the IS155-1200H-D at 1200cc-D/min, or 110 lbs/hr, at its standard 43.5 psi (3 Bar) test pressure. At the Dodge OE fuel pressure of 58 psi (4 Bar), flow increases to 1350cc/min, or 130 lbs/hr. The OE-pressure figure gives you and your tuner a clearer picture of the injector's available fuel delivery at the pressure used by the vehicle.
Data Match Technology for Precise Fuel Delivery
Fuel Injector Clinic precisely matches each IS155-1200H-D set using its proprietary Data Match Technology. Every injector is individually serial numbered, and the results are supplied on the included Data Match Sheet with detailed flow matching and latency information. Consistent injector behavior across all eight cylinders gives your tuner dependable data for calibration and helps support accurate, repeatable fuel delivery throughout the engine's operating range.
Short Pulse Width Control and Drivability
High-flow injectors still need to accurately deliver small quantities of fuel during idle, cruising, and part-throttle operation. The IS155-1200H-D combines increased fuel capacity with superior short pulse width control and state-of-the-art matching, helping the ECU maintain precise injector control at lower pulse widths. This makes the injectors easier to tune while supporting the drivability expected from a properly calibrated street or performance Dodge.
Built for E85 Performance Applications
E85 requires greater fuel volume than gasoline, making injector capacity especially important when power levels begin to climb. Fuel Injector Clinic specifically identifies the IS155-1200H-D as a strong choice for E85 applications. Its 1200cc-D flow capacity, High-Z electrical design, Data Match Technology, and short pulse width control provide a combination well suited to performance builds that need substantially more fuel without sacrificing precise injector operation.
Application-Specific Installation
Fuel Injector Clinic supplies the IS155-1200H-D with the O-rings required to fit the listed factory applications. Plug-and-play Dodge ECU data is also available to support calibration. If your Dodge uses aftermarket fuel rails, modified intake components, or another non-standard fuel system configuration, injector fitment should be confirmed before ordering.

FAQs
Why are the FIC IS155-1200H-D injectors rated at both 1200cc-D and 1350cc?
Injector flow changes with fuel pressure. Fuel Injector Clinic rates the IS155-1200H-D at 1200cc-D/min, or 110 lbs/hr, at 43.5 psi (3 Bar). At the Dodge OE fuel pressure of 58 psi (4 Bar), the injectors flow 1350cc/min, or 130 lbs/hr.
Are the FIC IS155-1200H-D injectors suitable for E85?
Yes. Fuel Injector Clinic specifically identifies the IS155-1200H-D as a great option for E85 applications. The combination of high fuel-flow capacity, Data Match Technology, and superior short pulse width control makes this set well suited to performance combinations requiring the increased fuel volume associated with E85.
