Cross-referenced parts are cataloged as fitting the same application but are not guaranteed to be identical to the original manufacturer part. Verify fitment against your OE number or VIN before ordering.
Reference/cross-reference numbers vary by engine, transmission, chassis and production date — not by number alone. Before ordering, compare your original OE number against C 31 121 number by MANN-FILTER listed above, and check the dimensions or specifications against your original part.
If you’re unsure, contact CarBus24 with your VIN or the number printed on your original part and we’ll confirm the correct match before you order.

Compare your original OE number against the OE Reference Numbers listed above, and check the dimensions or specifications against your original part.
