• Produced through a 15-step remanufacturing process in a U.S. facility
• Part number 812-11139 for accurate ordering and service matching

Detailed Description

This reman multi port fuel injector is intended for Chrysler, Dodge, and Jeep applications that use the listed OE-style injector design. It is a practical replacement for vehicles such as the Dodge Challenger, Dodge Charger, Dodge Durango, Chrysler 300, Jeep Grand Cherokee, and Jeep Wrangler, with fitment covering model years from 2011 through 2023. The injector is remanufactured to restore proper fuel atomization and electrical response, helping maintain stable engine operation and consistent fuel delivery. Part number 812-11139 is also referenced for service identification, and this part cross-references Monroe Shocks & Struts (e.g., 5038337AA, RL038337AA) for the same application.

What It Is Used For

• Restoring uneven fuel spray that can affect combustion quality
• Addressing injector wear that can cause rough idle or drivability concerns
• Replacing a unit with out-of-spec coil resistance or flow output
• Correcting fuel delivery issues tied to aging seals or o-rings
• Servicing a failed injector on supported Chrysler, Dodge, and Jeep models

Installation Notes and Tips

Use the vehicle-specific service procedure for injector replacement and follow the included installation instructions where provided in the application notes. Inspect the fuel rail, connectors, and sealing surfaces before installation, and replace the fuel filter when recommended for the application. Confirm fitment by year, make, model, and engine system before ordering.

Quality Assurance

GBR remanufactured OEM injectors are tested under multiple operating conditions to verify flow rate, spray pattern, coil resistance, form, fit, and function against OE specifications. The remanufacturing process is performed in a state-of-the-art U.S. facility for consistent service quality.
