E63s sparkplugs from weistec
hi, I have bought a step cooler spark plugs from weistec, they are too big for my E63s w213 according to my mechanic but weistec says I should put some grease on it and make it slide in and that many of their customers have bought for E63s and that there has been no problem

Guessing the bosch plug is the stock ones?

That Bosch one has a different insulator length than the other NGK plug. Also where is the terminal on the Bosch one?

There is a forum member here who does all sorts of wild AMG builds and I remember a thread from a long time ago about plugs. Stock ones, gapped down to .28 are perfectly fine for Stage 2.
