Technical characteristics of the N52B25A engine

The presented engine belongs to the Engines category and represents the popular N52 petrol unit with 218 HP, used in, among others, the BMW E60 and E90/E91 in 325i and 525i versions. The inline six-cylinder layout ensures smooth, quiet operation and good flexibility across the entire rev range. The petrol-based design promotes smooth power delivery, which translates into comfortable and dynamic driving both on the highway and in the city.

The N52B25A engine is valued for its refinement, the characteristic sound of an inline "six," and predictable behavior under load. The applied design solutions allow for efficient power utilization while maintaining an adequate torque reserve for daily use.

Application in BMW E60, E90, and E91 models

The unit was designed to work with BMW 3 and 5 Series drivetrains, particularly in the 325i and 525i versions. As a result, it is the right choice for replacing a damaged engine in vehicles from the E60 and E90/E91 family, where compatibility with the factory installation and accessories is required. Proper fitment for these models facilitates the installation process and reduces the need for additional mechanical modifications.

The engine comes from a vehicle dismantling process, which allows for the preservation of the original BMW unit specifications while maintaining a favorable cost-to-repair ratio. This solution is particularly interesting for users who want to restore the vehicle to full efficiency while maintaining the factory character of the drivetrain.

Condition, mileage, and benefits of choosing a used engine

The offered engine is in used condition, with documented mileage, which allows for a better assessment of its service history. The mileage, typical for units dismantled from this generation, provides a solid base for further operation in the vehicle, provided that proper installation and maintenance procedures are followed. Choosing a used OEM engine is often a cost-effective alternative to expensive overhauls or purchasing a new unit.

The main benefits of using this solution include:

• preserving the original operating characteristics of the BMW N52 engine,
• the possibility of matching by OEM numbers and interchangeable part numbers,
• an attractive ratio of purchase cost to the potential remaining service life,
• reduced vehicle downtime thanks to the faster installation of a complete unit.

Selection by OEM numbers and technical support

To correctly select an engine for a specific BMW vehicle, it is crucial to verify compatibility using the OEM number and reference numbers assigned to this unit. Proper matching based on factory markings minimizes the risk of problems with installation and integration with the vehicle's electronics. During the selection process, it is worth using catalog data and the VIN to ensure that the offered engine is suitable for your specific model year and equipment version.
