hmmm - my Ram is an 01 and uses the 5224 Autolite as a stock plug
design/heat range... I switched to 3923's a couple years ago. I
honestly don't remember what I set the gap to. Perhaps its time to pull
the plugs and see whats going on. Perhaps I should switch back to the
5224's and see if it runs better.
