Hello Chris,

I seam to recall that there was a dimensional issue with the AR4S. AR6S & AR8S. It was either the top shielded wire nut/thread size or the length of the barrel.

Hi Wes,
That's right, there missing the "S", I actually mean the AR6S.
I will try to figure out the shielded wire size and the length of the barrel and
the hot range!

Hi Wes,
Thank you very much for the sparkplug tables.
Soon I will come up with additional information.

AR6S spark plugs will not work with M38, M38A1, M37, M35. M135 etc. because of the design of the porcelain inside the barrel. The porcelain comes right to the top of the barrel and blocks the entry of the spark plug cable. ... Brian
