- Mahle equivalents (various part numbers depending on market)
Using these cross-references helps you find a matching filter for your car across different retailers.
How to confirm the exact OEM part number
Because BMW updated part numbers across production runs, the best way to confirm the precise OEM number for your car is to verify with the current filter or via VIN-based lookup:
- Inspect the removed filter for any stamped part number before disposal.
- Enter your VIN into the BMW parts catalog (via a dealer or trusted retailer) to pull the exact OEM designation.
- Ask your dealer’s parts department or use a reputable auto parts store’s cross-reference tool to match W670/2 or other cross-refs to your VIN and production date.
Having the exact OEM number ensures a perfect seal, proper fit, and guaranteed compatibility.
