<html><body>I'm sure that only your neighbor gets pissed when you drive by their house with bumblebee wired Healeys and they also have an old tube type radio or TV. Not sure that LED TVs or modern car radios are affected by engine noise, but all of it is RF so it might affect even your phone as well.

I use a non-resistor plug – Champion N12YC and 0.028” gap. I
too use a Lucas Sports coil. I always thought the resistor
plugs were to introduced to supress interference with car radios,
which I don’t have, but I am happy to be corrected on that.
I think plugs are unnecessarily changed too frequently.
I remove them once in a while (every few years) and clean and check
the gaps. I run them until they shows signs of
deterioration. I have never had a plug fail me in the
Healey.</p>

<p class="MsoNormal" style="margin-bottom:12pt;">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.<br><br>
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.<br><br><br></p>
