Plug blowout question
Could the "plug blowout problem" be related to Motorcraft plugs having only about 3/8" of threads? 
I compared one, (AWSF 22E), with a Champion 3401 and the Champion plug has twice the threads on the base. A properly torqued plug SHOULDN'T work it's way loose and I wonder if some of these plugs come up to the stop before they are tight enough.
I've read some pretty complex and technical ideas as to the cause of this; maybe it's simpler than that.
