That's cool folks; as long as I have the factory 7/70k warranty on the drive train in force I ain't looking to save money on a filter that is replaced rarely enough as it is. I do my own oil changes through the top with a Topsider and I'll be replacing my filter with a direct replacement part from Mercedes or Chrysler and saving the receipts. All the better if you have engine trouble down the road and the warranty is still in force...
