Not with Healey plugs but, as an aside, Ford had a massive problem a
few years ago (I should say, some Ford owners, namely those with
4.6L 'Modular' engines, had a problem). These are SOHC engines, and
their plugs were very long and skinny, and buried deep in the heads.
The gap between the chamber end of the plug and the head was very
narrow, and prone to 'carboning-up;' the problem was the plugs were
made in two pieces and, when someone tried to remove the
plugs--usually at 100K miles or so--the plug would pull apart,
leaving the bottom end stuck in the head (much fun ensued). Since I
had a 4.6L in my '08 Mustang I went, almost in a panic, to check my
car's plugs but, fortunately, it had a later version of the heads
that didn't bury the plugs so bad, and used a stronger, one-piece
plug. I changed the plugs at about 90K miles and it was a piece of
cake.<br>

Nope.<br>

The Champion plug that seems to be the most commonly available
off-the-shelf is RN12YC (I may have jumbled the letters). This for
a BJ8; my BN2 uses a different one, but I don't recall offhand
(N9?). The 'R' is for resistor, which I believe is about 15KOhms,
the 'C' is for copper (none of that fancy iridium or platinum
stuff for an old Brit car). I run them with 7mm stranded wire
secondaries, with resistor plug caps--again, about 15KOhms--and
have never had an issue, and I have a Pertronix points sets on
both my Healeys. They're good, with one re-gap, for over 25K miles
but, usually, if I go to the trouble to pull them I put new ones
in. Years ago I bought a bunch on sale for about $1/ea. at Pep
Boys.<br>
<br>
I've mentioned before that Champion brand is the go-to in light
aircraft piston engines; they have standard and 'fine-wire'
electrodes for engines that are known for lead fouling.<br>

<div style="color:black;font: 12pt Comic Sans MS, sans-serif;">I
have never had a spark plug let me down. Has anyone on the
list ever had an issue that could be attributed to a spark
plug? Using the incorrect spark plug for the application does
not count, nor does failing to change plugs when required.
Both of those are attributed to the failure of the person
responsible for maintenance. <br>
