Just slather on half a bottle and put them in finger tight! No need for a wrench or anything!

Knowing the average age of our crowd, the topic made me think this would be about hair transplants.

I don't know. Maybe it is?

NGK does NOT recommend using anti-seize on sparkplugs!

Below are the plugs that came out of my 2016 right before CFO last week. 1 year and 27,200 miles on them. With the new plugs I noticed no difference.. I still ride like shit.

Do not torque spark plugs.... if you use anti-seize, just a bit on the first 2-3 threads... they need a good ground to the engine so don't "insulate" them all the way up.... but I have seen plugs in for 50k that had carbon deposits on those bottom three threads that kinda scared me when I backed them out... perhaps remove them once a year to inspect and if good put them back in.
To properly install a new plug, screw in by hand until gasket (a crush washer) contacts the head. Quarter turn more, you're done... just like NGK tells you to do.
NGK also claims the coatings on the threads prevent them seizing....

Yup.

Had more than a few cars come in the shop with random cylinder misfire after the owner put new plugs in. Pull plugs and just a grain of rice worth of anti-seize, reinstall, and fixed. Aluminum heads were worse about it.
