Hi Proporsche,
some swear by 'no lubricant whatsoever on the threads of a spark plug' where others tend to disagree...
I use copper grease for its conductive characteristics but sometimes I get headwind...
never got a spark plug issue, but no idea if lubricant is necessary either, I just do it...
any idea why opinions do vary a lot on this subject ?
