intlautoparts.com lists two oil filters for my '55. One is a paper filter made by Hengst (A6002-105626) for $10.75, and the other is a fleece filter made by Mann (A6002-132856) for $16.83. Which filter is the right one for my use? Looks like all the AMG V8 engines use the same filter. Also, they don't show any parts for the SLK350, but the ML350 uses the same filters, so assuming the SLK350 filter is the same as the ML350, it would appear that both SLK engines use the same filter. How do these prices compare with purchasing at the dealer? Should I be concerned with not buying the filters at the dealer? Thanks.
