Green spark plugs?

[WhenGrantAttacks]

I was looking around the internet and found "e3" spark plugs. This is supposedly what they do.

-Produces up to 12% more power, reducing fuel consumption up to 13% while cutting harmful toxic emissions up to 58%
-By reducing carbon deposits, your engine will run cleaner and smoother and last longer

Any of you guys ever try or hear about them?

They don't sound too promising:

Indeed, sounds like BS

Yup, pretty much BS. If you're looking for the best spark plugs, try Denso Iridium Power. Iridium is a very strong metal, so tips can be made extremely small compared to copper or platinum. This results in a much denser spark that can ignite leaner mixtures than regular plugs. It also makes them last much, much longer. Average lifespan is about 40-60k for Iridium power, and long life (used in OEM applications) is up to 100K. Probably more under hypermiling. They're are a little under $10 each on eBay. These plugs worked wonders on my 86 Celica GT-S and 93 MR2 Turbo, making engine response quicker, and making the engine run smoother overall compared to new copper plugs. NGK also makes iridiums.
