I'm using NGK BKR5EIX 6341 plugs (Iridium IX line) with NGK plug wire set and I love them both.

It changes all the time
As a professional MB mechanic for over 30 years my preference has always been an NGK. They have always provided a superior spark plug which has never failed me. I can't tell you which number to use, but your parts store should have an NGK catalog to look up the proper plug. Don't waste your money on platinum, because your car does not require it. Many people think that more is better, and all they do is end up wasting money. Use exactly what your car calls for and you will be fine with the exception of tires.These cars were designed to drive on the highways in Europe which requires high-speed tires. High-speed means about 100 mph with short bursts of speed up to 125 mph.You won't be driving that fast here so S rated tires will be just fine, and they will meet the load rating.
