LOL - I just pulled plugs from my F150 (Gerald) that must've been in there for 60k+ miles. They were standard copper core autolites, and they still ran the engine, even with .100+ gaps. (I just bought the truck from a girl who couldn't reach the oil dipstick... Surely, she didn't do anything to it.)

I'm not really a fan of changing spark plugs for the most part. I feel that if they work, I should leave them in there. I do periodically pull them out, check/clean them, and re-check the gaps with feeler gauges.
LOL! So ou think we shouldn't spark plugs now?
