My take is that it
is mostly snake oil; but could be beneficial if your plugs are subject to
fouling. There is very likely very little additional power into the
spark; but the available power is concentrated into a very much shorter time –
instead of lighting up the spark for 30 millions of a second, it concentrates
it into about a billionth of a second (using their numbers). Whether
this is really advantageous to igniting the mixture; I don’t know, my guess is
probably not.
However; doing that
would definitely more likely fire a fouled plug. It is similar to holding a
gap between the plug wire and the plug. I remember from way back when I
was a kid and had an oil-burning Chevy that would foul plugs. Rigged
about a 3/8” gap between the plug wire and the plugs, and it would run
fine.
