The 1st Group Understanding Spark Plugs - The last line Racing/HiPerformance Spark Plug Heat Range Chart - I hope that is what you are looking for the chart is page 4-101

I guess what I'M looking for is a chart that would show the heat range. Or how the numbering works,
ie: is AR13
hotter than AR24? ECT.

Glen--- the Autolite numbering system is--- the lower the number the hotter the plug or the higher the number the colder the plug-- for example a AR13 would be a hotter plug than a AR24 would be or a AR 3332 is hotter than a AR 3333--not sure of how many choices you have in between AR13 and AR24------- FED 387

IF you go over to Yellow Bullet. In the naturally aspirated section they have a sticky at the top of the thread listings. One of them is a spark plug heat range chart. It includes the Autolite Champion and NGK Plugs in it.

the lower the number the colder the plug AR3932 is colder than a AR3933
