Hey, guys, I just replaced my spark plugs with new ones gapped at .45 (the Jeep is running fine with them, so I may gapp them to .55), but I wanted to verify that I am reading the ones I took out properly; to me, these seem fine, but what do you think?
They were on the rig for about 11K miles, if that helps. I am saving them as spares in case I ever need some plugs while wheeling...
