Default RE: 10mm plug questions


ORIGINAL: Tired Old Man

M4F might be an apt identifyer of a plug developed over several minutes of research. The ''M'' could represent ''minutes'', the ''4'' could relate to the number of minutes it could be expected to last, and the ''F'' could represent the first letter of the exclamation when the plug fails.

Hence the problem.

Ordered some NGKs from boats.net.

Thanks to all for the input and info.
