No, you should not lubricate spark plug threads. Lubricating can alter the torque readings and may cause over-tightening or under-tightening, leading to potential engine damage. Instead, use a small amount of anti-seize compound, if recommended by the spark plug manufacturer, to prevent the threads from sticking without affecting torque accuracy.
