Oil Sump BMW E87 E90 Engine Suction Pipe Strainer Hose N46 Petrol 7500328

Oil Sump BMW E87 E90 Engine Suction Pipe Strainer Hose is an original lubrication system component designed for BMW N46 series petrol engines. It is responsible for reliable oil suction from the oil sump and its stable delivery to the pump, which is crucial for engine durability. By maintaining factory geometry and flow diameters, the pipe ensures correct oil pressure throughout the engine's entire operating range.

Purpose and function in the lubrication system

The oil pump suction pipe with hose in the N46 engine is responsible for drawing oil from the bottom of the oil sump and transferring it to the pump, which then distributes the lubricant through the engine channels. In BMW petrol engines, the proper operation of this component is particularly important at higher RPMs, where stable oil pressure is required.

Using a dedicated oil pump suction pipe allows for maintaining factory flow parameters, which reduces the risk of insufficient lubrication of the bearings, camshaft, or timing components. This technical solution is designed specifically for the operating characteristics of BMW petrol engines, which translates into safe operation of the power unit.

Construction and fitment for the N46 engine

The oil pump suction pipe in this version is structurally matched to the architecture of the N46 engine and the shape of the oil sump used in the BMW E87 and E90. The proper profiling of the pipe ensures:

• correct positioning of the suction strainer at the lowest point of the oil sump,
• stable mounting to the pump body and engine block,
• maintenance of the oil suction system's tightness.

Thanks to the preservation of the original geometry, the component works with the factory oil sump without the need for modifications, which facilitates installation and reduces service time. This is especially important during work related to the regeneration or replacement of lubrication system components.

Operational characteristics and benefits of use

In BMW petrol engines, such as the N46, the lubrication system operates under varied conditions – from city driving to prolonged highway loads. Using the correct oil pump suction pipe helps maintain:

• stable oil intake during changes in engine speed,
• appropriate pressure levels throughout the entire lubrication system,
• proper cooling and lubrication of moving engine parts.

For the user, this means more predictable engine operation and a reduction in the risk of costly failures resulting from momentary drops in oil pressure. Combined with regular oil and filter changes, the oil pump suction pipe is an essential element of preventive maintenance.

Condition, origin, and service application

The offered component comes from the BMW parts group and is intended for use in petrol engines where maintaining factory lubrication system parameters is required. A used component of this type is particularly effective in:

• routine repairs after damage to the oil sump or pump,
• engine overhauls,
• preventive maintenance at high mileages.

Thanks to the preservation of the original design, the oil pump suction pipe allows for installation in accordance with service documentation, without the need for adaptation or modification of other system components.
