Wait what? I am running 37psi in my tires (dodge recommends 35psi)
The max on my tires is 80psi.

For some reason I can't get into my albums to load pics. But anyway, I just changed all 16 plugs on my truck. And wouldn't you know it, first new plug I took out of the box was smashed shut! No gap at all! After checking all 16 I found less than half were at the recomended .045 gap. What happened to the little cardboard or plastic tubes they used to put over the ends of plugs to protect the electrode from this stuff?

I just reinstalled the factory champion's. Mine were so f'ed up because the previous owner obviously never did routine maintenance.

If you do that, you will wear your tires out right down the middle!

I changed my intake plugs on my '08 4.7. None of the plugs were gapped correctly.
