Hi Dennis,
yeah, I was off on the CR thought.
hmmmm...
rapidly changing the gap.
I seldom have any issues at all with waterbxer spark plugs ..
I don't notice them changing much at all ...
though perahps these other types do.
when Bosch first came out with platinums ..
earlyh 80's perhaps..
they were saying 'never change plugs again' ..
but they are not 'that perfect' really ...I've seen a few bad ones
About the only time I ever see a waterboxer spark plug is for a
compression test.
I use good ones...
Bosch or NGK and just never seem to have any issue with them.
More plug wire problems than spark plug wires.
you welcome. lol.
