Damn thats a good tip.

Measured gaps and discovered that the NGK plugs were at 0,75-0,8mm while the Bosch are all at 0,7mm.
Is that part of the problem?

The old plugs look alright?!
Damn that is very good info! Thanks (again) JerryJS8 !

Looking foward to see the rest of your build and maybe learn more useful tips for mine
