Fuel Injector Clinic 1200cc High-Z Fuel Injector Set (IS155-1200H) - Dodge 5.2L / 5.9L / 4.7L / 6.4L
Give your performance Dodge the fuel capacity needed for serious horsepower with the Fuel Injector Clinic IS155-1200H 1200cc High-Z Fuel Injector Set. This complete eight-injector set flows 1200cc/min, or 110 lbs/hr, at 43.5 psi (3 Bar) and 1350cc/min, or 130 lbs/hr, at the Dodge OE fuel pressure of 58 psi (4 Bar). Designed around modern saturated, high-impedance injector technology, the IS155-1200H combines substantial fuel capacity with excellent linearity, superior short pulse width control, and predictable response for easier tuning and strong drivability. It is also an excellent choice for E85 performance applications that demand considerably more fuel volume.
Each IS155-1200H set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Every injector is individually serial numbered, with detailed flow matching and latency results supplied on the included Data Match Sheet. These injectors use a Jetronic electrical connector, so a connector conversion is required for the listed applications. PGTJETR8 solder-in pigtails are included, or optional PADPJtoU8 plug-and-play adapters can be selected for installation without cutting or soldering the factory harness. This 1200cc injector set was previously sold under part number IS155-1100H, and plug-and-play Dodge ECU data is available from Fuel Injector Clinic.

1200cc Rated Flow and 130 lbs/hr at OE Fuel Pressure
Fuel Injector Clinic rates the IS155-1200H at 1200cc/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. Because injector flow changes with fuel pressure, understanding both ratings gives you and your tuner a more accurate picture of the fuel capacity available at the vehicle's operating pressure.
Data Match Technology for Precise Fuel Delivery
Consistent injector behavior across all eight cylinders is critical when fueling a high-output engine. Fuel Injector Clinic precisely matches each IS155-1200H set using its proprietary Data Match Technology. Every injector is individually serial numbered, and its results are documented on the included Data Match Sheet with detailed flow matching and latency information. This gives your tuner valuable injector data for calibration while helping provide consistent, repeatable fuel delivery across the engine.
Short Pulse Width Control and Drivability
A high-flow injector still needs to accurately meter small quantities of fuel during idle, cruising, and part-throttle operation. The IS155-1200H combines substantial fuel capacity with superior short pulse width control and state-of-the-art matching, helping the ECU maintain precise control at lower injector pulse widths. The result is an injector designed to support serious performance while retaining the tunability and drivability needed in a properly calibrated street-driven Dodge.
A Strong Choice for E85 Performance Builds
E85 requires greater fuel volume than gasoline, making injector capacity a critical consideration as horsepower increases. Fuel Injector Clinic specifically identifies the IS155-1200H as a strong choice for E85 applications. Its 1200cc flow capacity, High-Z electrical design, precise matching, and short pulse width control provide a well-rounded combination for performance builds that need substantially more fuel without overlooking low-load injector control.
Jetronic Connector with Two Installation Options
The IS155-1200H uses a Jetronic electrical connector and requires a connector conversion in the listed applications. The set includes PGTJETR8 solder-in pigtails that can replace the existing injector connectors on the vehicle's wiring harness. For an installation that does not require cutting or soldering the factory harness, optional PADPJtoU8 plug-and-play adapters can be used instead. Fuel Injector Clinic uses this configuration to provide brand-new, unused injectors rather than relying on remanufactured or core-program injectors.

FAQs
Do the FIC IS155-1200H injectors require a connector conversion?
Yes. The IS155-1200H uses a Jetronic connector. PGTJETR8 solder-in pigtails are included with the injector set, or optional PADPJtoU8 plug-and-play adapters can be used to install the injectors without cutting or soldering the factory wiring harness.
Is IS155-1200H the same injector set previously sold as IS155-1100H?
Yes. Fuel Injector Clinic identifies the current IS155-1200H as the replacement for the previous IS155-1100H designation. The current injector is rated at 1200cc/min, or 110 lbs/hr, at 43.5 psi and 1350cc/min, or 130 lbs/hr, at the Dodge OE fuel pressure of 58 psi.
