Purpose and compatibility

The offered cylinder head is dedicated to the M47N2 engine used in popular BMW 1, 3, 5, and X3 series models of the E60, E83, E87, E90, and E91 generations. As such, it provides the correct foundation for repairing the upper part of the engine in vehicles with this engine type, without the need for structural modifications.

As a component from the Cylinder Heads group, the part is responsible for proper cylinder sealing, valve guidance, and interaction with the timing and cooling systems. Choosing an original BMW cylinder head allows you to maintain compliance with factory tolerances and the operating characteristics of the M47N2 diesel unit.

Technical characteristics and role in the engine

The M47N2 cylinder head is a key component of the upper engine section, integrating intake and exhaust ports, valve seats, and the combustion chamber space. Its condition determines:

• stable compression in every cylinder,
• proper valve guidance and interaction with the timing system,
• efficient heat dissipation from the combustion chamber area,
• maintenance of a seal between the engine block and the cooling and lubrication systems.

In the case of an M47N2 engine overhaul, using an original BMW cylinder head reduces the risk of fitment issues, leaks, or improper valve operation. This is particularly important for diesel engines, where thermal and pressure loads are higher than in petrol units.

Condition, origin, and advantages of using BMW parts

The presented cylinder head is an BMW OEM component, which means it maintains the original port geometry, valve seat placement, and accessory mounting points. This makes it possible to restore the factory engine performance characteristics without the compromises typical of many aftermarket replacements.

As a used part, the cylinder head is a cost-effective solution for engine repairs, especially in cases of cracks, overheating, or excessive wear of the previous component. Combined with appropriate workshop processing (surfacing, leak testing, valve seat regeneration), it allows for building a durable and technically sound upper engine assembly.

Why choose an original BMW M47N2 cylinder head

Choosing an original cylinder head for the M47N2 engine primarily ensures consistency with the factory engine design and predictable behavior after installation. The correct placement of ports, proper wall thickness, and compatibility with the engine block reduce the risk of operational problems after an overhaul.
