HERE IS A CHART that shows lots of plugs and to be honest yours look like the 3rd row from the top first or second from the right... marked 'Good'.

Can someone clarify what I might not bee seeing??

The info I see on the web seems to indicate to me my first set in question was possibly a bit lean. This second set in on now looks completely different to be vs the first set. Truck now seems to run the same now with the 14's as it did with the first set of 18's. I'm guessing I'm better to keep running the cooler ones anyways. I will recheck them in a few hundred miles when I fill up.

Next issue to move onto us the fuel smell that I get swamped with as I accelerate aggressive.
