Randall:
AMSOIL has an online parts catalog to specify the correct oil filter for your Mercedes. I can't help you because both of your requests did not include a year model which is needed to populate that online catalog.
Please visit this URL:

From that web page, there is a link: "Find the Filter That Fits Your Vehicle"
After clicking on the Find Filter link, a catalog will open and allow you to choose the Year, Make, Model and Engine size.
AMSOIL may or may not have their own proprietary filter, but will usually have a recommendation for either an AMSOIL synthetic filter OR an oil filter from one of their partners.
You can rest assured that if no AMSOIL filter is listed, the recommendation is a quality filter designed to be used with the AMSOIL lubricants for maximum engine protection.
Please don't hesitate to email me directly for more information.
