Interesting spark plug maybe
There's an S2000 owner on another forum who let this company borrow his car for a spark plug comparison research.
He's telling me that they dynoed an additional 18hp from this plug change on a stock S. I having a hard time believing it.
He's using something called a pulse plug. I'd post the plug website but I don't want to plug them
Anyone familiar with them

From what I've read, they are basically 33% more powerful than a normal plug, but a normal plug makes more than enough power for spark for our car, so they aren't worth the cost.

Here's their website and please everyone note.....this is not a recomendation but rather skepticism.
In theory that's awful cheap hp for the cost if it works and doesn't break off, fits right and all that stuff.
pulse plug
Anyway I'll keep watching the thread over on S2you know....

Once ignited, I don't see how the flame front propogation speed of an air/fuel mixture has anything to do with the wattage of the ignition source?
They claim 1 million watts over a time of 2 billionths of a second. That's 0.0005 watts per second.
They say a "normal" spark plug delivers 50 watts over 30 milltionths of a second. That's 0.0015 watts per second, three times as much total power as theirs.

It's probably junk science, like the turbinator. But let's give junk science a try:
[JunkScience]It gives off a larger/stronger spark the ignites the air/fuel mixture quicker. This enables the ECU to advance the timing farther and get a bump in HP.[/JunkScience]
EDIT: I typed the info above before following the link, but wait, here's a quote from the site: "Pulse plugs simply ignite fuel better" What a load of

I do like the video of the expanding flame front.
I've seen similar gadgets in another hobby of mine; muzzleloading rifles. That industry has come up with hotter, bigger flame front producing caps to ignite the charge. They actually do give a more efficient burn of the powder charge and I have chronographed higher muzzle velocity using them. Hmmm...
