Intended Use and Technical Characteristics

The N47 injector set has been designed for precise fuel delivery in Diesel engines, ensuring stable engine operation and proper running characteristics at idle and under load. The injection system design in these units requires highly accurate components, making the use of original BMW parts crucial for maintaining correct combustion parameters.

This product is from the BMW OE line, meaning it is factory-matched to the fuel supply system in E87 LCI and E90 models, specifically the 120d and 320d versions. This ensures the correct injection pressure, fuel spray pattern, and proper integration with the engine control electronics.

Benefits of Using the N47 Injector Set

Using a complete injector set instead of individually selected parts ensures the cohesive operation of the entire system. In practice, this includes:

• Improved Engine Stability – uniform fuel delivery to all cylinders reduces vibrations and uneven engine running.
• Optimized Fuel Consumption – properly functioning injector nozzles contribute to efficient fuel utilization.
• Reduced Risk of Secondary Damage – a healthy injection system minimizes stress on components such as pistons, valves, and the diesel particulate filter.
• Better Throttle Response – correct pressure and injection timing translate to predictable acceleration.

Condition, Origin, and Reference Number Compatibility

The set is used, offering a favorable balance between repair cost and maintaining original BMW specifications. For workshops and individual users, this means an economical replacement option while preserving the engine's factory performance characteristics.

The product comes with a dedicated OEM part number and an extensive list of interchangeable numbers, facilitating compatibility verification with specific engine versions and vehicle model years. It is advisable to compare the markings with your vehicle's documentation or the removed part before purchase to confirm full assembly compatibility.

Professional Application in Diesel Servicing

In N47 engines, properly functioning injector nozzles are critical for operational safety, emissions, and engine longevity. The injector set for BMW 120d and 320d allows for a comprehensive fuel supply system repair, which is particularly important when experiencing symptoms such as starting difficulties, power loss, or excessive smoke.
