I've read that dielectric grease is applied to the
non-metal parts of the plug and/or that surface
of the boot (where accessible) that slips over the plug.
And some websites say to put the grease on the
metal terminal as well.
I can understand the use of a non-conductive
material to prevent fusion/adhesion of a non-contact
point as w/ the ceramic jacket vs rubber of the boot
but not of the metal-to-metal contact mating surfaces.
Yet, people say that they do this.
The service manual makes no mention of dielectric
grease although it does rec anti-seize cmpd.
BTW, is a Cu-based anti-seize suitable for spark
plugs or is a higher temp Ni-based cmpd
