I'm running a Jabiru, and they use the NGK D9EA plug, or the Iridium
plug of another number. I haven't run the Iridium yet, as I'm still on
my 2nd set of the number mentioned. The Iridium's are $10 each at my
car dealers, or $8 each at the Jabiru dealer. I'm told they idle
smoother. At $64-80 for a change, I'm gonna think about this for a bit.
My first set of D9EA's lasted for well over 100 hours, and I only
changed them because I wanted to look at them, and had another new set
waiting to go in. I may try the Iridium's down the road a piece.

You are right Lynn,
I got rid of my plug cleaning machine many years ago.
It didn't use sand, but any abrasive can produce
damage if not thouroughly cleaned out. (Mine
supposedly didn't harm the ceramic. If I remember
correctly, it used ceramic chips)
If you are buying aviation plugs at around $10 each
and 2 per cyl, cleaning them may still make economic
sense.
And if you modify them a Deke suggests, you need to
carefully clean out any debris, just like the blasting
material, as well.
So, the need to clean plugs can still come up and that
is why I made the suggestion.
