Trying to find local source after accidentally cracking one and realized I had to order spares, no parts store had one in stock. I called Champion to see if they would help but was told they are discontinue the racing line of plugs, Anyone else heard this? Does anyone had any real dimensions? I did some rough measuring the depth into the threads and height of electrode on few sets of different plugs I had around here. I started this with a chart from Autolite to convert. I dug thru master catalogs looking for similar plugs and added them just for comparison Last edited by Dart451; 07/19/23 05:21 PM.

I may have one or more of the plugs you want to sell replace Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

In theory, there is no difference between theory and practice. In practice, there is.

This just made me think about what's really different between the plug brands and cross reference chart Just edited the top post to show what I measured, thought made the heat range of the plug.
