The spark plug threads have a special plating on the threads to prevent seizing up over time. Spark plug makers are aware of the possibility of dis similar metals causing problems so they have added anti seize plating to the threads.
Do NOT put anti-seize on the threads, as you may over tighten them and shear the thread portion off.
From an NKG bulletin.
For spark plugs with special metal plating simply do not use anti-seize on initial Installation; All NGK Spark Plugs are manufactured with a special trivalent Zinc-chromate shell plating that is designed to prevent both corrosion and seizure to the cylinder head; Thus eliminating the need for any thread compounds or lubricants.
Additional Information
NGK recommends only using spark plugs with metal plating on all aluminum head applications to prevent damage to the head and plug. Metal shell plating acts as a “lubricant” which breaks away from the main body of the spark plug during removal, preventing damage to the spark plug and or threads in the cylinder head.
