Just thought I'd run this by everybody, did an air filter change on my 2007 SLK55 AMG P30. Put in some new AEM dry flow air filters which have no oil in them, was always a K&N fan but their so loaded with oil thought I'd try something else and got a deal on Ebay. I encountered something that I have not found any information about. Came across "Post Air Filters" that look like cabin air filters. So I took them out considering I probably don't need "Post Air Filters", if anybody has any advise about this please chime in. Pictures are in a sort of DIY timeline.
Thank You
