I've run over 150K miles on Champion plugs with nary an issue (and will
continue to do so); RN12YC for the BJ8 and whatever the recommended is
for a 100M (RN10C?). With Pertronix Ignitors in both, I run slightly over
'book' value (0.025") at 0.028" and both run very well (I also run
stranded copper wire secondaries, so the 'R' is important, plus the plug
caps have a resistor in them as well). My one-time auto shop teacher
father maintained whatever spark was sufficient to ignite the mixture was
adequate--mixture and compression took it from there--but a larger gap
induces a 'hotter' spark which may be beneficial with leaner mixtures and
at higher engine RPM (but has less margin as the electrode erodes). A
larger gap requires the coil to produce more secondary voltage to jump
the gap; a sports coil may be required to produce a consistent spark. 12K
miles on plugs is fine in my experience--as long as the engine is in good
nick--and they can be cleaned and re-gapped at least once. Sandblasting
is a no-no as it will pit the ceramic insulator and can cause issues.
I came across a YouTube video by David Vizard where he claims E3 Diamond
'Split Fire' plugs produced slightly better mileage; yep, E3 makes a plug
for Big Healeys (6-cyl only, I think). I've heard rumors that counterfeit
NGK plugs are in the market.

1. I was looking through my library of files on Healey topics and
saw that we were all over the place on plug gaps=E2=80=A6..all =
the way
up to 0.035=E2=80=9D. So what=E2=80=99s the opinion there??
2. And which plug? Seemed to be mostly between NGK=E2=80=99s BP6ES=
&
BP5ES. Was a hold-out for their B8EGV 5627 but that was
dismissed fairly vigorously by Jeremy Welch as being way OTT
for normal road use.
3. And, I have 12,000 miles+++ as plug replacement mileage so long
as they still look and perform OK. Any thoughts?
