Alright folks, this is an interesting modification to spark plugs.
They use OEM spec plugs and drill a small hole in the ground strap to create an ultra-sonic wave in the air/fuel mix.
The discussion on the web-site is interesting reading.
On our A4, I have made changes that have made the engine purr, especially the temperature control valve and heat exchanger that keeps it steady at 180*. And the prop (10x7) that gives us a comfortable 1800 RPM and 5.5kts cruise speed (GPS).
I'm curious to hear feedback on the science of these spark plugs.
