BMW Oil Filter Housing Gasket 11428637821 – Genuine BMW Seal

Product Description

The Genuine BMW Oil Filter Housing Gasket 11428637821 is designed to provide a reliable seal between the engine oil filter housing and the engine block, helping prevent engine oil leaks around the oil filter housing assembly.

BMW part number 11428637821, also written as 11 42 8 637 821, replaces the earlier BMW gasket 11427537293. BMW parts catalogues also identify it as an engine oil filter adapter gasket, oil filter housing gasket, cover gasket, housing assembly gasket or oil filter housing seal.

This is an important distinction when listing the product online: 11428637821 is a gasket/seal, not an engine oil filter element.

What Does the BMW Oil Filter Housing Gasket Do?

The oil filter housing gasket creates a sealed connection between the oil filter housing and the engine block. Over time, the original gasket can harden, shrink or lose its sealing ability due to repeated exposure to engine oil and heat.

A deteriorated gasket can result in:

Oil leaking around the oil filter housing
Visible oil residue around the engine
Oil dripping onto surrounding engine components
Low engine oil level if the leak becomes significant
Burning-oil smells when leaking oil reaches hot components
The need for repeated engine-oil top-ups

Replacing a worn gasket helps restore the proper seal and prevent further oil leakage.

ECS Tuning describes this component specifically as the gasket that seals the oil filter housing to its attachment point on the side of the engine block.

BMW Engine Compatibility

Part 11428637821 appears across a range of BMW engines and applications. Catalogue data includes applications involving BMW N20, N52, N54, N55 and S55 engines, although exact fitment depends on the vehicle and engine configuration.

Examples of applications documented in BMW catalogues include:

BMW 2 Series
BMW 3 Series
BMW 4 Series

For example, RealOEM records the part on BMW F01 730i and 740i, as well as the F80 M3 with the S55 engine.

Because the same gasket can appear across different engine families, VIN verification is recommended before ordering.

Common Signs of a BMW Oil Filter Housing Gasket Leak

If your BMW has an oil leak around the front or side of the engine, the oil filter housing gasket should be inspected.

Common signs include:

1. Oil around the oil filter housing
Fresh or accumulated engine oil around the housing can indicate a deteriorated gasket.

2. Oil smell from the engine bay
Leaking oil can reach hot engine components and create a noticeable smell.

3. Oil level dropping
A persistent external oil leak can cause the engine oil level to fall between services.

4. Oil residue on surrounding components
Oil can spread from the housing area to nearby components, making the original leak difficult to identify without proper inspection.

5. Visible gasket deterioration
During inspection, an old gasket may appear hardened, flattened or damaged.

Why Replace the Gasket With a Genuine BMW Part?

Using the correct gasket is important because the oil filter housing operates within the engine’s lubrication system and is exposed to engine oil and heat.

The genuine BMW 11428637821 is designed specifically for the applicable BMW oil filter housing configuration. It is also the current replacement for 11427537293 in BMW parts catalogues.
