I see these things advertised in snowest. Is there any advantage over NGK?

I would be afraid of deto, that is a lot more metal on the electrode to get hot and pre-ignite!
On the other hand, they did prove a touch more hp, but brake fuel consumption dropped on a nasty small block chevy, Horsepower TV did a show on it a while ago.
