Application and Compatibility

The presented BMW gasoline injector has been designed as a fuel system component for popular models such as E46, E87, X3 E83, Z4 E85, and E90/E91. By maintaining factory flow parameters and spray characteristics, the part helps preserve the proper operation of the engine unit and stable performance.

The injector belongs to the Injector Nozzles category, meaning it is designed for use in a precise, high-pressure gasoline fuel system, maintaining the correct spray pattern and opening time.

Construction and Technical Characteristics

As an original BMW component, the injector is made from materials resistant to gasoline and high temperatures within the engine bay. The construction of the body, seals, and electrical connector is adapted to the factory injector rails and wiring harnesses used in the mentioned BMW generations.

• Precise Fuel Delivery – optimized needle opening and closing time ensures uniform cylinder fueling.
• Adapted for Gasoline Engines – the spray pattern geometry is designed for gasoline-powered units, with the correct fuel cone shape.
• Factory Electrical Connector – allows for direct connection to the vehicle's wiring without modifications.

Benefits of Using an Original Injector Nozzle

Using an original BMW injector to replace a worn-out component restores the proper functioning of the fuel system. This directly impacts:

• Stable Idle Operation – uniform fuel delivery minimizes engine RPM fluctuations and vibrations.
• Improved Throttle Response – the correct amount of gasoline across the full load range enhances acceleration dynamics.
• Optimal Fuel Consumption – the correct fuel-air mixture composition helps maintain factory fuel consumption levels.
• Reduced Exhaust Emissions – uniform fuel atomization facilitates complete combustion in the cylinder, supporting catalyst operation.

Component Condition and Installation Aspects

The injector is categorized as used BMW injector nozzles, allowing for an economical repair of the fuel system while maintaining original manufacturer specifications. Before installation, a standard service procedure is recommended: inspect the seats in the manifold or cylinder head, verify the condition of the seals, and check the fuel system for leaks.

Due to the nature of gasoline injector operation, maintaining cleanliness during installation and ensuring proper seating in the rail and socket is particularly important to guarantee system tightness and repeatable fuel dosage.

Diagnostics and Technical Knowledge

Although the described component pertains to a gasoline system, many principles of injector diagnostics are similar to those for diesel systems.
