Technical Characteristics of the Injector

The presented BMW fuel injector belongs to the Injector Nozzles category and is structurally adapted for use in gasoline fuel systems. It is responsible for atomizing fuel in the combustion chamber at a precisely defined time and quantity, which is crucial for:

• maintaining the correct mixture composition across the entire RPM range,
• stable engine operation during acceleration and constant speed driving,
• reducing fuel consumption through precise dosing,
• lowering exhaust emissions through proper mixture combustion.

As an aftermarket OEM component, the injector is structurally matched to the factory BMW fuel system, which facilitates installation and allows for the preservation of original engine performance parameters.

Application and Compatibility

The BMW E81 E87 LCI E90 E91 E92 Fuel Injector Inject has been designed to work with gasoline engines used in popular 1 and 3 Series models. Thanks to assigned part numbers and interchangeable numbers, technical verification of compatibility with a specific engine version and vehicle year is possible.

Before purchasing, it is recommended to compare the markings with the service documentation or the existing component in the vehicle. This will confirm that the injector nozzle will work correctly with the engine control system and the fuel rail.

Benefits of Using an Original Injector Nozzle

Choosing an original aftermarket BMW gasoline injector is a solution that combines economic aspects with the preservation of factory engine performance parameters. The most important advantages include:

• factory fit to the cylinder head port and fuel rail,
• correct spray pattern consistent with engine control unit maps,
• stable engine starting when cold and hot,
• even operation across all cylinders, which reduces vibrations and misfires.

In cases of symptoms such as rough idling, power loss, increased fuel consumption, or mixture-related errors, a functional gasoline injector is one of the key components for restoring proper fuel system operation.

Component Condition and Installation Aspects

The offered injector nozzle is an aftermarket item and is classified as a used OEM component. Before installation, standard service procedures are recommended, such as checking the seats, seals, and the cleanliness of the fuel system, to ensure proper operation after installation.

The injector is designed for installation in place of the factory component, which simplifies the mechanic's work and reduces service time. A correctly selected component helps avoid adaptation issues and ensures consistency with the factory engine control unit software.
