These came off of a 2016 E63S with 25k miles on them. Barely any oil consumption, stock tune and driven hard. Most plugs have oil on the threads, some more than others and couple of them are dry. Tips look good, no oil and gaps look about the same on all.
Seems normal, oil on threads, light colored, some darker colored, some build up and the gaps not being tremendously bigger than stock seems to be in line with used plugs.

Yea looks good for sure, i was expecting them to be worse. I wonder why some threads are dry tho and most have oil.
