Has anybody tried these?? It states the in general, you should expect torque to increase by 4 to 12% and realize a significant improvement in fuel economy.

Its hard to trust something like this, after seeing so many ridiculous spark plug "developments" and related claims, but I believe this may be legitimate. They are made here in Albuquerque, and what the website fails to mention(with my short glance) is Sandia national Laboratories developed the technology and licensed it to them or developed it with them as a partnership.

In theory it should be great, just don't want to shell out that kind of loot for some plugs.
