Them telling you that you need irridium is most likely because they can get more money out of you. The plugs you've got now are perfect!

Regarding the previous issues... Yes, running lean for a long time can burn up the plugs a bit. The seafoam will also foul things up as a side-effect of doing it's job. So what you saw on the plugs is nothing I would be concerned about. Their condition is what I would expect and now that you've corrected those conditions, I would expect it to continue running happy and glad.

agsf12pp? that is the number I have found that should be right for our trucks. I am trying to still see if anyone knows what the heat of the plug should be? Low or cold, 3 5? etc. based on engine knowledge not Autozone answers.

I know some tuners that run a dyno and I will ask them.
