I can't see how this indexing does any good, unless the idea is to
"douse" the electrodes with the mixture. After all, the intake valve
has long since closed by the time the plug fires, making the orientation
of the side and center electrodes irrelevant. Can anyone elaborate on
the supposed benefits of indexing the spark plugs?
