[QUOTE="SoonerP226, post: 2134804, member: 26737"] I changed the original factory plugs (double platinum) on my '89 T-Bird SC at 75K miles (this would have been in '93). The things looked damn near new, and were still gapped well within spec; the factory double-platinums in my Lincoln had over 90K miles on them and were also clean and well within the gap range when I replaced them. They've not made the copper plug that will go that long, particularly given the high-energy ignition systems in modern cars. [/QUOTE]
