This part number, FJ1230K, is also listed as a cross-reference to Bosch 0445120187 for the same application.

Common Problems This Part Can Address

• Hard starting on diesel direct injection systems
• Rough idle caused by injector wear
• Excessive smoke from poor fuel atomization
• Loss of power from inconsistent fuel delivery
• Fuel trim or combustion imbalance related to injector performance

Installation Notes and Tips

Verify connector style, clamp mounting, and injector part number before installation. Clean the injector bore and surrounding area thoroughly, and inspect the sealing surfaces before fitting the included O-rings. Because this is a diesel direct injection component, proper torque procedures and fuel system cleanliness are important during service.
