Note: Full compatibility requires verification via BMW ETK or VIN lookup.

3. Working Principle

• Sealing Function: Compresses between the oil filter housing and engine block to prevent high-pressure oil leaks.

• Dynamic Adaptation: Expands slightly under heat/pressure to maintain seal integrity during engine operation.

• Failure Impact: A worn gasket causes oil leaks, potentially triggering low oil pressure warnings or engine damage.
