One doesn't set gap on platinum plugs.
The factory plugs come out of the box ready to install.
It's been this way for German cars for decades, even for conventional plugs. Bosch, of course.

Sure ... what I posted in 2010 is correct. This assumes you’re using plugs purchased from Mercedes, I.e. 004 159 18 03 26. Take them out of the box and install them. Feel free to check them if you must. And, if you’d like to know the gap check your owners manual.
