Purpose and compatibility

The offered engine is intended for BMW 1 Series E87 and BMW 3 Series E90/E91 models with the 150 HP N46B20B gasoline unit. The design was developed for daily operation, ensuring the right balance between dynamics and economy. The unit is compatible with factory BMW solutions, which facilitates installation in place of a damaged engine without the need for structural modifications.

Technical characteristics of the unit

The engine belongs to the Engines category and is a modern, inline four-cylinder gasoline unit. This configuration ensures good balance, predictable behavior under load, and easier maintenance compared to more complex systems. The use of gasoline promotes quiet operation and quick revving, which is particularly noticeable in city traffic and during dynamic acceleration.

An additional advantage is the relatively low mileage of the unit, which translates into less wear on moving parts and potentially longer service life after installation in the vehicle. As a result, the engine is a favorable alternative to rebuilding heavily worn units.

Condition, origin, and benefits of choosing a used engine

The offered unit is a used BMW engine, which allows for a significant reduction in repair costs compared to purchasing a new component. In practice, this means the ability to restore the vehicle to full efficiency while maintaining a reasonable level of investment. The engine comes from dismantling, which is a standard and accepted source of functional mechanical components in the automotive industry.
