Engine temp won't be a big deal, I'd rather do it cold to avoid burned hands.
Never seen one snap on a 112, always a first time I guess.
I'd stick with the Bosch plugs, find out the current recommendation from MB, then shop them out.
I'd avoid the other brands. MB originally offered Bosch, Beru, and Champion numbers, I think they decided to just go Bosch.
It'll run alot better with new plugs.
What's wrong with the sunroof?
