i always use a very sparing amount of antiseize on spark plugs, as mentioned too much of it lowers the heat range of the plug and makes it slightly more prone to fouling. this isnt new to K series Nissan engines, upright VW air-cooled engines go back 50 years with the same problem...

not that it's always needed, but if you use a very sparing amount of silver grade (NOT nickel grade) antiseize on a plug you can install it like that in virtually any engine without ill effect.
