Technical Characteristics of the Injector System

The presented kit comes from the injector nozzles category and is designed for engines powered by diesel fuel. The injector system design ensures:

• Precise fuel delivery – crucial for maintaining the N47 unit's proper power and torque.
• Appropriate injection pressure – supporting even mixture combustion and reducing smoke.
• Stable operation at low and high RPMs – which translates to smooth acceleration and predictable vehicle behavior.
• Better control over exhaust emissions – with proper configuration of the entire fuel and exhaust system.

The solution based on original BMW technology allows for maintaining parameters close to factory specifications, which is important when servicing modern diesel units.

Condition, Origin, and Benefits of Use

The offered BMW injector system kit is a used market component, allowing for economical fuel system repair while maintaining the factory design. For many users, this is a favorable alternative to purchasing new parts, especially for older E81, E87 LCI, and E90 series models.

Using this injector kit allows, among other things, for:

• Restoring proper fuel system operation after injector failures.
• Reducing cold start problems, typical for malfunctioning diesel injector systems.
• Minimizing the risk of uneven engine running and power drops resulting from incorrect fuel delivery.

Diagnostics and Operation of the Diesel Injector System

When replacing components from the injector nozzles category, it is advisable to perform a full fuel system diagnostic to verify the condition of other components. Symptoms such as louder engine operation, jerking, increased fuel consumption, or smoke may indicate the need for intervention in the injection system.
