Fuel Injector for Jeep Cherokee

Standard Ignition FJ1439 is a new top-feed MFI fuel injector for 2018-2020 Jeep Cherokee applications. It is built for precise fuel metering, stable engine operation, and consistent delivery under heat and corrosion exposure.

Key Features

  • New MFI fuel injector for gas applications
  • Top-feed system with female blade terminal connection
  • Stainless steel calibration slide and spring assembly helps resist internal corrosion
  • Precision wound and trimmed solenoid windings support accurate ECU-controlled fuel delivery
  • High-temp Viton O-rings are included for sealing under elevated engine temperatures
  • Black injector body finish

Detailed Description

Standard Ignition FJ1439 is engineered to support smooth engine operation by delivering balanced fuel flow across the injector circuit. The flow-matched design helps maintain even fueling, which is important for drivability, fuel economy, and emissions control on the Jeep Cherokee and other listed applications. The stainless steel internal calibration components are selected to reduce corrosion inside the fuel control body, while the solenoid windings are trimmed for efficient electronic command from the vehicle computer. This part cross-references 2-39715 and 800-2507N for the same application.

What It Helps Solve

  • Rough idle caused by inconsistent fuel delivery
  • Misfire conditions related to injector flow imbalance
  • Hard starting from poor atomization or restricted injector performance
  • Excess fuel consumption tied to uneven metering
  • Elevated emissions from inaccurate fuel delivery

Installation Notes and Tips

Fits 2018-2020 Jeep Cherokee, N/A. Confirm the injector connector style, top-feed fuel system layout, and OE part number before installation. Replace worn seals during service and verify fuel pressure, electrical continuity, and leak-free operation after installation. Part number FJ1439 may also be referenced during catalog lookup for Jeep Cherokee fuel injector replacement.

Quality Assurance

Standard Ignition focuses on replacement electrical and fuel-system components built for consistent fit and function. FJ1439 uses corrosion-resistant internal materials and high-temperature sealing components to support long service life in demanding engine bay conditions.
