There is a debate about whether or not to use anti-seize when installing spark plugs. The official position of Autolite on this question is to consult the service manual for the vehicle being repaired and use anti-seize only where the original manufacturer recommends it. The nickel coating on most modern spark plugs provide added protection from seizing in aluminum cylinder heads and has made anti-seize less important in spark plug installations. Anti-seize can alter the tightening torque up to 20%, increasing the risk of breakage. It can also create heat transfer and electrical conductivity concerns. This video is sponsored by Autolite.

Have you ever wondered in a rear-wheel-drive vehicle how the engine spinning in the center of the car can spin the wheels that are perpendicular to the engine?

Well it is a mystery how that happens. Additionally in that same space we change the ratios of revolutions and the torque available to spin everything.
