Cheap and genuine
Cheap and is genuine. Best filters for mercedes.

Two 0 rings, small one for stem base, large one for seal at top of filter cap, use persuasion.
Fits my Mercedes 2005 E280 CDI exactly. Don’t forget to lightly spread a bit of engine oil around both replacement 0 ring seals, with your finger, when fitted to the oil filter body. Otherwise the large 0 ring might grab its seating when tightening the filter body into its housing, distorting the ring.
