I worked on Mercedes in the early 70's. We used to throw the stock spark plugs away when prepping a car and put in NGK's.
I've NEVER checked a Bosch plug and found it out of spec. This being since the 1970s.
Moving from the USA automotive scene to the German is a positive move--the USA is a third world country in comparison.
