Purpose and compatibility

The presented oil pump pipe is designed for use with the S55 petrol engine, found in BMW M2 F87 LCI, M3 F80, and M4 F82/F83 models. The component's construction is adapted to the high thermal and mechanical loads typical of M-series units with increased power and torque.

Its original BMW origin ensures that factory dimensional tolerances are maintained, providing proper oil routing within the engine block and full compatibility with the stock oil pump and other lubrication system components.

Function in the lubrication system

The oil pump pipe is responsible for the controlled delivery of the lubricant to the pump and subsequently to the engine's oil channels. In S55 units, which often operate at high RPMs, proper oil flow is essential for:

• maintaining stable oil pressure across the entire rev range,
• ensuring adequate lubrication of the bearings, crankshaft, and timing system,
• reducing the risk of seizing moving parts during intensive track or sports use,
• dissipating heat from the most heavily loaded areas of the engine.

Selecting the correct oil pump pipe is particularly important for turbocharged engines, where thermal loads are higher than in standard naturally aspirated units.

Component characteristics and benefits

As a part from the Oil pumps and parts group, the pipe is made of material resistant to long-term contact with engine oil and fluctuating operating temperatures. The shape and cross-sectional diameter are optimized to minimize flow losses, which helps maintain proper system pressure.

Key benefits of using an original oil pump pipe in an S55 engine include:

• maintaining factory lubrication parameters with stock or increased power,
• consistency with other oil system components,
• reducing the risk of leaks resulting from ill-fitting aftermarket replacements,
• maintaining predictable engine behavior under high-load conditions.

Condition, verification, and selection by part numbers

The item is offered as a used part, which allows for economical repair or rebuilding of the lubrication system while maintaining original BMW specifications. Before installation, a standard visual inspection of the flow channels and sealing surfaces is recommended, in accordance with the manufacturer's service procedures.

To select the correct oil pump pipe for a specific BMW M2, M3, or M4 configuration, it is worth using the OEM numbers and interchangeable numbers assigned to this component. Detailed markings can be found in the product technical specifications section.
