Detailed Description

GBR’s reman multi port fuel injector line focuses on restoring OEM-level performance for BMW fuel injection service. Part Number 852-12157 is engineered for direct replacement use on 1996-1999 BMW 328i, 1996-1999 BMW 328is, 1996-1999 BMW M3, 1997-1998 BMW 528i, and 1997-2000 BMW Z3 applications. This part cross-references Bosch 0280150440 and BMW 13641703819 for the same application.

Each injector is remanufactured through a controlled process and then tested to confirm consistent fuel delivery characteristics. That makes this injector a strong option when servicing BMW fuel injection systems that need stable idle quality, proper atomization, and accurate metering.

What It Helps Address

• Rough idle caused by inconsistent injector spray
• Fuel trim issues related to uneven fuel delivery
• Misfire concerns tied to injector performance
• Hard starting from poor injector operation
• Reduced engine smoothness in BMW 328i, M3, 528i, and Z3 fuel systems

Installation Notes and Tips

Confirm the injector connector style, fuel rail fitment, and OE part number before installation. Replace aged seals during service and follow BMW fuel system procedures for depressurizing the rail, checking for leaks, and verifying injector operation after installation. Use the vehicle’s service information for final testing and adaptation steps where required.

Quality Assurance

GBR remanufactured injectors are processed in a U.S.A. facility and tested to meet or exceed OE specifications for critical operating characteristics. Part Number 852-12157 is built to support consistent fuel delivery in the listed BMW applications.
