Based on this, I’m guessing I just pulled the original plugs! I’m just over 192k miles.

I think it was closer to 1/8”.

Does anyone have an idea when the part number was changed? I just pulled a set of 41-110 plugs out of thecopcar, but don’t know the age of them.

Mine had 41-110 in it when I changed them in 2019. I replaced them with 41-110, so they were still available in 2019. I'm guessing the numbers changed in late '19 early '20

Ha! That’s okay. She bit me enough already.

Your truck requires a blood sacrifice too? Glad I'm not alone!
Wondering if the number change is from switch to NGK manufacture?

Yep. That’s #8 I’m holding.
