"pulse" spark plugs - any good?

Saw an ad for them in a popmech magazine
They have a capacitor inside and are supposed to create a spark 20,000 times more powerful than a standard spark plug, thus burning the fuel faster and more thoroughly and creating higher PSI

http://www.pulstarplug.com/

So has anyone used these or know if they're any good?

It has this warning on they're page:
CAUTION: Pulstarô model recommendations are for stock, unmodified engines. If you have added an aftermarket turbocharger, supercharger, nitrous or any other product that increases displacement or compression to your engine you will require a colder heat range pulse plug in order to avoid possible damage to your engine.

Spark plug tech can be summed up easily:

1) Most important is the heat range of the plug. Plugs with the wrong heat range will cause uneven combustion or detonation.
2) Platinum or iridium (both in the same family on the periodic table) resist fouling over long periods of time at the expense of greater electrical resistance.
3) Multi- prong (cathode) since electricity will ALWAYS follow the path of least resistance, you can only have one spark regardless of marketing pictures that appear to show more than one spark. These just resist fouling over long periods of time and give a more consistent spark.
4) Everything else is marketing.

the most ill spend on plugs and have are the Brisk ones from steeda... they are pretty nice, and i did notice my car idle better afterwards.

but anyways, it just seems that that spark plug has a capacitor in it... and on our cars with 4 idividual coils, our cars dont really loose power to the plug, but i could seeing those being more affective on an older engine with long ineficient spark plug wires...

but not on ours, the plug has a direct line of fire from the coil.

Its kinda reminds me of a distributor in some ways; cuz I think distributers use capacitors in pulse instead of straight electricity.... IMO.

Probably best for like old muscle cars.

The purpose of a capacitor in the distributor type ignitions using points was to buffer the voltage going through the points so they didn't get fried. A capacitive discharge ignition can be used with a distributor type system and works on the same principe of storing energy and then discharging the stored energy at once when the coil is fired.
