Fuel Injector Clinic 1000cc High-Z Fuel Injector Set (IS155-1000H) - Dodge 5.2L / 5.9L / 4.7L / 6.4L
Step up the fuel capacity of your Dodge performance build with the Fuel Injector Clinic 1000cc High-Z Fuel Injector Set. The IS155-1000H includes eight saturated, high-impedance injectors rated at 1000cc/min, or 85 lbs/hr, at 43.5 psi (3 Bar). At the Dodge OE fuel pressure of 58 psi (4 Bar), these injectors flow 1040cc/min, or 100 lbs/hr. Excellent linearity and short pulse width repeatability provide the predictable injector response needed for accurate tuning and strong drivability while delivering substantially more fuel for higher-output combinations.
Fuel Injector Clinic precisely matches each IS155-1000H set using its proprietary Data Match Technology. Every injector is individually serial numbered, with detailed flow matching and latency results provided 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 IS155-1000H requires no injector connector conversion. Plug-and-play Dodge ECU data is also available from Fuel Injector Clinic.

1000cc Rated Flow and 100 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 IS155-1000H at 1000cc/min, or 85 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 1040cc/min, or 100 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
High-flow capacity alone does not make a great performance injector. Consistent operation across all eight injectors is critical for accurate fueling and calibration. Fuel Injector Clinic precisely matches each IS155-1000H 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 to give your tuner valuable data for building an accurate calibration.
Short Pulse Width Control and Drivability
A 1000cc injector still needs to respond accurately when the ECU commands small quantities of fuel during idle, cruising, and part-throttle operation. The IS155-1000H combines excellent linearity with strong short pulse width repeatability and state-of-the-art matching. This predictable response helps make the injectors easier to tune while supporting the smooth drivability expected from a properly calibrated street or performance Dodge.
Drop-In Size and Plug Installation
The IS155-1000H 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 IS155-1000H injectors rated at both 1000cc and 1040cc?
Both ratings are correct because injector flow changes with fuel pressure. Fuel Injector Clinic rates the IS155-1000H at 1000cc/min, or 85 lbs/hr, at 43.5 psi (3 Bar). At the Dodge OE fuel pressure of 58 psi (4 Bar), the injectors flow 1040cc/min, or 100 lbs/hr.
Do the FIC IS155-1000H injectors require a connector conversion?
No. Fuel Injector Clinic specifies the IS155-1000H as drop-in for both size and plug in the listed factory applications, so no injector connector conversion is required.
