Application in BMW M2, M3, M4 models

This turbocharger and manifold are designed for the petrol engines in the BMW F87 M2 LCI, F80 M3, and F82 M4 models, covering cylinder ranges 1-3. Integrating the turbine with the exhaust manifold allows for the retention of factory exhaust gas flow characteristics, resulting in predictable throttle response and dynamic performance across the entire rev range.

This item comes from the Turbochargers & Parts category, making it the right choice when replacing the factory supercharger system in the sporty versions of the 2, 3 and 4 generation F Series. The OEM design makes it easy to fit to the original mounting points and stock hardware installation.

Construction and technical characteristics

The system combines the turbocharger and exhaust manifold for the first row of cylinders in a single housing. This configuration:

• reduces exhaust energy losses between the head and the turbine,
• ensures stable thermal conditions in the hot zone,
• makes it easier to maintain the appropriate boost pressure during dynamic driving.

The solution is adapted to work with a petrol engine, which means properly selected channel geometry, rotor characteristics and sealing parameters in terms of higher temperatures and specific exhaust gases in petrol-powered units.

Condition, provenance and fit

The product is listed as used, meaning it comes from a vehicle disassembly and is intended for continued use after proper assembly and verification of compatibility with the specific engine configuration. Original BMW origin guarantees compliance with factory manufacturing tolerances and compatibility with stock accessories, hoses, and mounts.

To ensure compatibility with a specific car, it is worth verifying the markings in the technical specifications tab – both the OEM part number and related interchangeable numbers are available there, making it easier to compare with service documentation or an existing component.

Benefits of using an original BMW turbocharger

The use of the original manifold turbocharging system in BMW M sports models brings a number of practical benefits:

• Factory fit – maintaining the original manifold and turbine geometry supports the correct operation of the engine controller and the standard boost maps.
• Stable power characteristics – proper exhaust flow and appropriately selected turbine parameters help maintain predictable acceleration and repeatable performance.
• Trouble-free installation – OEM design reduces the need for modifications, which shortens service time and reduces the risk of leaks in the exhaust and intake systems.
• Consistency with other components – the turbocharger works with the factory cooling, lubrication and boost pressure control systems.
