Detailed Description

Bosch 62858 is a high-pressure direct gasoline injector engineered for BMW engines that rely on GDI fuel delivery. It supports accurate atomization and fuel metering in applications such as the 2014-2016 BMW 550i, 2014-2016 BMW 650i, 2015-2016 BMW M5, 2014-2016 BMW X5, and later BMW 650i, M6, X6, and X7 models listed in the fitment data. If you are searching for a BMW fuel injector for 650i xDrive, M6 Gran Coupe, or X5 direct injection service, this Bosch injector is built for those exact applications.

Bosch’s long history in gasoline injection systems makes this part a practical choice for restoring proper fuel delivery on BMW direct-injection engines. The injector is intended for vehicles that use one injector per cylinder and is listed with two included O-rings for sealing at the fuel rail and cylinder head interface.

Common Issues This Part May Resolve

• Hard starting caused by poor fuel atomization
• Rough idle from inconsistent injector spray or fuel metering
• Misfire conditions related to a failing direct injector
• Fuel trim imbalance from restricted or leaking injector performance
• Loss of power or hesitation under load in GDI-equipped BMW engines

Installation Notes and Tips

Verify engine code and injector part number before installation. Direct injection systems operate at high pressure, so relieve fuel pressure and follow BMW service procedures before removing the injector. Inspect the sealing surfaces, replace worn seals as needed, and confirm the injector is seated correctly to prevent leaks or drivability concerns. This Bosch fuel injector 62858 should be matched to the exact vehicle application shown in the fitment data.
