So the "Diamond Fire Sparkplug" is the new "Splitfire"?
Don't forget to magnetize the gas.

Thanks, I had already read that incredible information. It says the plugs may reduce fuel consumption up to 13% and may increase power up to 12%.

Remember those little propellers you could put in the air intake stream?

Polonium tipped spark plugs?

Magic pills a driver put in the fuel tank?

Intake manifold gaskets with little screens?

I do want to believe, but every time I buy into the new miracle product it seems to be a bust. But hey, maybe this time...

I checked my Autolite catalogue heat range section, and it shows 23 as coldest, 26 hottest. Autolite's numbering system seems pretty incomprehensible though, for other styles of plugs the hotter plugs have lower numbers.
