Purpose and compatibility

The offered BMW 1 3 Series e87 e90 e91 120i 320i 150HP Complete Engine N46B20B WARRANTY is intended for BMW 1 Series E87 and 3 Series E90/E91 models in 120i and 320i versions with 150 HP. The unit's design was developed with dynamic yet economical driving in mind for everyday use. The four-cylinder inline layout ensures smooth operation, good refinement, and predictable torque characteristics, which is particularly important in compact and mid-size cars.

Construction and operating parameters

The engine belongs to the family of modern BMW petrol units, based on a four-cylinder block with advanced valve control and precise fuel delivery. The use of petrol as fuel allows for smooth acceleration, predictable throttle response, and comfortable operation across the full rev range. Four cylinders help reduce the unit's weight, which positively affects vehicle balance and handling.

A significant advantage is the unit's mileage, which remains at a level typical for engines with high potential for further operation. For the user, this means the possibility of continued, intensive use of the car while maintaining an appropriate durability reserve, provided that proper maintenance and suitable consumables are used.

Thanks to the preservation of the original BMW specification, it is possible to:

• restore the factory performance of the 120i / 320i versions,
• maintain compatibility with the existing electrical installation and vehicle equipment,
• reduce installation time compared to adapting other units.

The engine from this series is well-known to workshops specializing in the BMW brand, which facilitates diagnostics, maintenance, and any further service work. It is a practical solution for users who want to restore the car's full efficiency without the need for costly drivetrain modifications.

Condition, origin, and purchase safety

The offered power unit comes from dismantling and is sold as a used BMW engine. This type of solution allows for a significant reduction in repair costs compared to purchasing a new component, while maintaining the manufacturer's original specification. The engine is complete in terms of the block with accessories typical for this reference, which facilitates its further installation in the vehicle.

An additional advantage is the provided start-up warranty, which gives real security during the first start-up after installation. Before purchasing, it is worth verifying the unit's compatibility with the specific vehicle equipment version and consulting the installation with an experienced workshop to fully utilize the potential of this power unit.
