Application and Compatibility

The offered BMW injector nozzles are dedicated to N52 and N52N petrol engines used in BMW E60, E65, E81, E85, E87, and E90 models. Using an original solution from the same engine family allows for maintaining factory fuel delivery parameters, correct atomization, and predictable throttle response.

The injection system in N52/N52N engines is sensitive to component quality, which is why using original injector nozzles from this series is crucial for:

• maintaining smooth idle operation, without misfires,
• stable power and torque across the entire RPM range,
• correct mixture composition and cooperation with lambda sensors and the engine control unit.

Technical Characteristics of the Injection System

The presented injectors operate within a petrol fuel supply system adapted to the specifics of N52/N52N naturally aspirated engines. The nozzle design ensures precise fuel atomization in the combustion chamber, which translates to:

• efficient mixture combustion under various loads,
• reduced fuel consumption through proper dosing,
• lower exhaust emissions due to correct catalyst operation.

Original BMW injector nozzles are designed for a specific type of fuel, so their use in a petrol engine helps avoid issues with leaks, over-fueling, or a lean mixture.

Condition of the Component and Benefits of Choosing Used Injector Nozzles

The offered set comes from a dismantled vehicle and is sold as used BMW injector nozzles. This type of solution is beneficial for users who want to restore the fuel system's functionality while maintaining reasonable costs, relying on original OEM components instead of aftermarket alternatives with uncertain parameters.

Choosing used, original injectors allows for:

• maintaining compliance with the factory specification of the engine control unit,
• minimizing the risk of adaptation and coding issues with the injectors,
• maintaining predictable engine behavior in various operating conditions.

Diagnostics and Prevention for the Injection System

When replacing injector nozzles in petrol engines, it's worth paying attention to symptoms typical of worn or dirty injectors: uneven cold running, increased fuel consumption, power loss, or the smell of unburnt fuel. Although the presented component relates to a petrol engine, many principles of fuel injection system diagnostics are common.
