AC 45 XLS. "4" means 14 mm. "5" is heat range which is mid range (ranges run about 2 thru 8), very good for usual normal customary passenger car operation.

IF possible use the AC 45XLS. Why???? Welllllllllll. Just look at all of the confusion about OTHER brand (ANY other brand) of plugs. I am using the AC 45XLS in my 56 Executive.

Want to know what the XLS stands for too????
