What It Helps Address

• Hard starting caused by poor fuel atomization in a direct injection system
• Rough idle from inconsistent injector spray performance
• Misfire conditions tied to fuel delivery imbalance
• Fuel trim issues related to a worn or restricted injector
• Loss of power from inadequate high-pressure fuel delivery

Installation Notes

Verify engine code, emissions configuration, and injector marking before installation, especially on Chevrolet Impala, Cadillac ATS, and Chevrolet Malibu applications. Confirm the Bosch 62844 part number and match the vehicle’s direct injection fuel system requirements before replacing the injector. Clean the injector bore and inspect sealing surfaces so the included O-rings seat correctly.
