Anyone know what the difference is between the 41-110 and the 41-162 plugs?

I thought that too.52
As far as I know it was basically just a part number change.
When I changed my plugs last year, it had the 41-110 in it, so that's what I got to replace them.
I was just looking at stuff on Advanced Auto website and when looking at the 41-110 it says it doesn't fit my vehicle, but says the 41-162 does, so just curious.

From what I could find out is the original number was 41-985 superseded by 41-110 which were superseded by 41-162. Any of them should be fine.

I think the new numbers are assigned when there's a design change and or vendor change. Running 41-985s in mine, have a spare set of 41-110s.
I know from looking at pictures in online discussions that the 41-162 is noticeably shorter than the 41-110 from seat to tip of electrode, I heard it’s about 3/8”.

Online specification info shows these measurable differences....
41-110 vs 41-162
Insulator height 25mm vs 24.7mm
Pre-gap size 1.025mm vs 1mm
Everything else seems to be the same

The guys that had them side by side said the length from the seat where they sit against the head to the tip of the electrode was 3/8” difference but I don’t think that matters.

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.

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

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.You 8k to go, put them back in....200k plugs
Your truck requires a blood sacrifice too? Glad I'm not alone!
Wondering if the number change is from switch to NGK manufacture?
