The MB filter is exactly the same except has a MB logo and doesn't have the two black depth lines so you know the filter is in all the way. They figure a MB tech has to know without the lines. It also comes in a fancy box with a hologram seal closing it.
It also is likely identical media to the Purolator Boss. You can find the Boss media slammed by the Fram Ultra folks. I think they sleep with their Fram Ultras. They know more than MB about oil filters.
