Fuel Injector Clinic 1440cc High-Z Fuel Injector Set (IS156-1440H) - 2008-2013 Dodge 4.7L / 2003-Present 5.7L
Give your high-horsepower Dodge the fuel capacity it needs without giving up the injector control that matters during everyday driving. The Fuel Injector Clinic IS156-1440H is a complete set of eight 1440cc/min saturated, high-impedance injectors for 2008-2013 Dodge 4.7L and 2003-present Dodge 5.7L applications. Each injector flows 1440cc/min, or 140 lbs/hr, at 43.5 psi (3 Bar) and 1700cc/min, or 160 lbs/hr, at the Dodge OE fuel pressure of 58 psi (4 Bar). Positioned between FIC's 1200cc and 1650cc injectors, the 1440cc provides serious fueling capability while retaining the linearity, short pulse width control, and idle performance needed for a properly tuned street or performance build.
The IS156-1440H uses stainless alloy valve construction for broad fuel compatibility, including pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Each injector 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. FIC flow tests and rates these injectors at 43.5 psi (3 Bar) and 90 degrees F fuel temperature using calibration fluid. Drop-in fitment with the factory-style connector eliminates the need for a plug conversion, while plug-and-play Dodge ECU data is available from Fuel Injector Clinic to support calibration.

1440cc Flow with 160 lbs/hr at OE Fuel Pressure
Fuel Injector Clinic rates the IS156-1440H at 1440cc/min, or 140 lbs/hr, at its standard 43.5 psi (3 Bar) test pressure. At the Dodge OE fuel pressure of 58 psi (4 Bar), available flow increases to 1700cc/min, or 160 lbs/hr. Because injector flow changes with fuel pressure, both ratings are important when sizing a performance fuel system. The 58 psi specification provides an application-relevant reference for the injector's available fuel flow at the stated Dodge OE fuel pressure.
Serious Fuel Capacity with Street-Friendly Control
The 1440cc High-Z injector fills the gap between Fuel Injector Clinic's 1200cc and 1650cc offerings, making it an excellent option when a build needs more capacity than a 1200cc injector can provide without immediately stepping to the larger 1650cc size. FIC specifically designed the 1440cc injector to provide excellent idle performance in street-driven vehicles while supplying the additional fuel required by higher-horsepower combinations running gasoline or E85.
Data Match Technology
Eight large injectors need to behave consistently if the ECU is going to maintain accurate fueling across all eight cylinders. Fuel Injector Clinic precisely matches each IS156-1440H set using its proprietary Data Match Technology. Every injector is individually serial numbered, and its results are supplied on the included Data Match Sheet with detailed flow matching and latency information. This provides valuable injector-specific data for calibration while helping maintain consistent fuel delivery throughout 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 IS156-1440H combines excellent linearity with superior short pulse width control and repeatability, giving the ECU predictable injector response across a wide operating range. With proper calibration, that control helps deliver the idle quality, throttle response, and street drivability expected from a performance Dodge while retaining the fuel capacity needed when engine load and horsepower demand increase.
Gasoline, E85 and Race Fuel Compatibility
The FIC 1440cc High-Z injector uses stainless alloy valve construction and is compatible with a broad selection of fuels. Fuel Injector Clinic specifies compatibility with pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. That versatility makes the IS156-1440H a strong choice for performance combinations that may run anything from pump gasoline to E85 or specialized race fuel.
Drop-In Factory-Style Connector
The IS156-1440H features easy-to-install, drop-in fitment with the factory-style electrical connector in the listed applications. No injector plug conversion is required, eliminating the need to cut or solder the factory injector wiring. Fuel Injector Clinic also supplies the O-rings required for the listed factory applications, and plug-and-play Dodge ECU data is available to support proper calibration. If your vehicle uses aftermarket fuel rails or another non-standard fuel system configuration, confirm injector fitment before ordering.

FAQs
What does the 160 lbs/hr rating mean on the FIC IS156-1440H?
Fuel Injector Clinic rates the IS156-1440H at 1440cc/min, or 140 lbs/hr, at 43.5 psi (3 Bar). At the Dodge OE fuel pressure of 58 psi (4 Bar), injector flow increases to 1700cc/min, or 160 lbs/hr. Both specifications describe the same injector operating at different fuel pressures.
Can the FIC IS156-1440H injectors be used with E85 and race fuel?
Yes. Fuel Injector Clinic specifies the 1440cc High-Z injector as compatible with pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Its stainless alloy valve construction provides broad fuel compatibility for street and race applications.
