Must be that’s why Ford recommends changing the sparkplugs at 100k miles ;-)
And most don’t realize that running with excessive spark plug gaps puts undue stress on the ignition COPs.
When the COPs generate maximum voltage and still can’t get that voltage to ground (via the sparkplugs gap), it sets up oscillations in the COP’s secondary windings which eventually melts the insulation of the windings and suddenly the COPs start failing.
