Pudendum Inspector aka FORZDA 1
Just decided to replace them because about to head out on long road trip. They are the original plugs from 2018 at new vehicle purchase. I tuned the truck within 1500 miles of new, so 80+000 miles on them. Never had a, not even one, misfire event while laying down many 12.5sec 1/4 mile passes and 140mph top speed runs. You know, just sayin the Ford iridium plugs are pretty good and those people replacing plugs a lot are doing it for fun, running bad fuel, or a bad tune.
They all measured 0.33” gap, except cyl 1 was 0.35”. I checked the new ones set to 0.30” and all is well. Pic of old plugs
