Another tightening option is to follow the sometimes included packaging info that shows tightening 1/4 to 1/2 turn beyond finger tight. This works fine for NEW plugs but ONLY before the gasket gets compressed. If I decide to reuse a sparkplug then always with a torque wrench as posted above.
Thanks Pete C. I got the job done.
