It doesn't make sense to pay extra to put Japanese plugs in a Mercedes. My dealer said stock is Bosch or Beru. When I was in he had the Berus so that's what I put in. I wonder why the platinum +4's are so much less than the other Bosch plugs on Fastlane? I don't think you'd go wrong with either choice.
