Anyone ever heard of or used these things?

I picked up a set, since the guy who makes them is only a couple miles from my house. They are going in the bike Saturday when I finally get off my ass and do the 10K service on Elvira (at 11K miles :: blush :: )
Looking at them, they are just your basic NGK plugs, but there is a small shaped hole drilled through the ground electrode into the center electrode. I talked to the guy who designed them (Mechanical and Acoustic engineer with a string of patents) and his claim is that during the compression stroke, the cup in the center electrode fills with fuel, and as the plug fires it forms a jet of gas that goes through the hole (which is chamfered and looks like a very small jet nozzle) causing it to act as a whistle. That in turn sends a high frequency ultrasonic sound wave through the combustion chamber ahead of the flame front, breaking up fuel droplets in the A/F mix, homogenizing it for better combustion.
The theory seems sound enough, from what I know of physics. I'll post a review in a month or so, when I have a couple thousand miles on the plugs- I'm just curious to see if anyone else has tried these things.
Oh- the price is I think $8 each and if you order them, try and do it online- the guy is deaf as a post and it's a PITA to actually speak to him :: chuckle ::

I am intrigued... I dont see it doing anything at all but it is worth a shot. Keep us posted.
