Product Details

GBR’s Reman Multi Port Fuel Injector line focuses on restoring OEM injector performance for BMW engines that require precise fuel delivery. This injector is remanufactured to meet or exceed OE specifications, making it a practical replacement when drivability issues trace back to fuel atomization or injector wear. The 852-12238 part number is used across multiple BMW 3 Series, 5 Series, X3, X5, and Z4 applications, including 2006-2013 BMW 328i and 2008-2013 BMW 128i listings.

This injector is intended for direct replacement in the listed BMW fitments and is supported by application notes that call for fuel filter replacement on certain models. For BMW 328i, 328i xDrive, 328xi, and 128i applications without SULEV emissions, the fitment notes specify replacing the fuel filter when the injector is replaced and referencing Technical Bulletin TB-0119-EFS.

What It Helps Address

• Hard starting caused by inconsistent fuel delivery
• Rough idle from uneven injector spray pattern
• Misfire conditions related to injector performance
• Poor fuel atomization affecting throttle response
• Fuel trim issues tied to worn or out-of-spec injectors

Installation Notes

Use the vehicle-specific installation instructions for the listed BMW applications. Confirm the engine and emissions configuration before ordering, especially on 128i, 328i, 328i xDrive, and 328xi models with the noted SULEV exclusion. Follow the application note to replace the fuel filter when required by the bulletin, and inspect sealing surfaces before installation.

Quality Assurance

Each injector is remanufactured using a controlled 15-step process and tested to confirm OE-level performance targets for flow, spray, resistance, and fit. New external seals and o-rings are included to support proper sealing during installation.
