Purpose and Application

The BMW fuel injector is designed to work with N54 and N63 engines, fitted in models such as the 335i and 550i of the E90, E92, and F10 generations. The nozzle's design is adapted to the requirements of turbocharged units, where stable pressure and uniform fuel atomization across the entire load range are crucial.

A properly selected injector directly influences:

• correct formation of the fuel-air mixture in the cylinder,
• maintaining smooth engine operation at idle and under load,
• throttle response and refinement during dynamic acceleration.

Construction and Operating Characteristics

The injector nozzle from this series has been developed as a precision component, operating under high pressure in the gasoline fuel system. The construction of the body and the atomizing tip is optimized for:

• precise fuel atomization in the combustion chamber,
• dose repeatability under varying engine load,
• stable operation at high temperatures and under prolonged thermal stress.

Original manufacturing in accordance with BMW standards allows for the preservation of the engine unit's factory performance parameters, which is particularly important in high-power density turbocharged engines.

Benefits of Using an Original Injector Nozzle

Using an original BMW injector nozzle to replace a worn component helps to mitigate common fuel system issues, such as rough cold running, power loss, or increased fuel consumption. A correctly selected injector supports:

• stable fuel system pressure and predictable engine behavior,
• maintaining proper exhaust emissions in accordance with factory specifications,
• improved engine refinement at low and high RPMs.

This ensures the fuel system remains consistent with the factory engine control unit calibration, which is important for both stock and mildly modified vehicles.

Part Condition and Selection

The offered BMW fuel injector comes from the BMW Injector Nozzles category and is a used part, offering a cost-effective solution while maintaining the original manufacturer's specifications. This type of part is particularly attractive to users who want to maintain the factory engine configuration without resorting to aftermarket replacements with uncertain parameters.

When selecting an injector, it is advisable to pay attention to compatibility with the engine code and body generation. An original component from this series is designed as a component that works with the factory control unit, facilitating installation and reducing the need for additional adaptation.
