Purpose and compatibility with the N47 engine

The presented exhaust manifold is designed to work with N47 diesel units installed in BMW E60, E87 (including LCI versions), E90, and E91 series. Properly shaped exhaust channels enable efficient cylinder scavenging, which helps maintain the correct operating parameters of the turbocharged diesel engine. The manifold's construction is adapted to the thermal loads typical of modern diesel units, which is important for long-term operation in various road conditions.

Technical characteristics of the exhaust manifold

As an element from the Exhaust manifolds category, this model is responsible for collecting exhaust gases from individual cylinders and directing them to the rest of the exhaust system. A properly selected manifold:

• ensures uniform exhaust flow from each cylinder,
• reduces local thermal stress in the cylinder head area,
• supports the proper operation of the turbocharger and exhaust gas recirculation system,
• helps maintain stable operating parameters of the diesel engine.

Thanks to its factory geometry and appropriately selected channel cross-sections, the manifold is prepared to work with a diesel exhaust system where both flow and resistance to high temperatures and pressure pulsations are essential.

Condition, origin, and advantages of using a used part

The offered BMW exhaust manifold comes from the used parts segment, which allows for economical exhaust system repair while maintaining the manufacturer's original specifications. Choosing a dismantled component is a solution that combines:

• factory fitment for a specific generation of diesel engine,
• preservation of the original exhaust flow characteristics,
• cost reduction compared to a new component.

Using an original BMW exhaust manifold minimizes the risk of leakage problems, improper fitment, or incompatibility with engine accessories. This is particularly important in diesel units, where the exhaust system works with the turbocharger, filters, and an extensive emission control system.

Benefits of a properly selected exhaust manifold

In N47 diesel engines, the right exhaust manifold has a direct impact on the durability and refinement of the engine. Using the correct component allows you to:

• maintain correct exhaust pressure at the turbocharger inlet,
• reduce the risk of cracks resulting from uneven heating,
• maintain stable operating parameters across the full load range,
• facilitate future service and diagnostics of the exhaust system.
