Maybe they are for Australian models?What could cause a spark plug gap to close? I replaced a set of Ruth's that had maybe 15k miles on them, and the gap had closed to ~0.020 or so. When I installed them, they were pre-gapped to 0.024 - 0.025 (same as the new ones), and I had left them as-is. Usually they open after time, not close...
