Are 'pulse spark plugs' legit?

Got this from the www: "Pulse plugs have the appearance and fit of standard spark plugs but they also contain a capacitor. The capacitor increases the sparks intensity, more efficiently igniting fuel and increasing power and gas mileage".

Sounds good (too good?), but I never heard of them before...

 

Pulstar Plugs I think you mean. I'm not willing to pay $25 per plug to find out, I'll use that money for gas instead.

 

I agree... I think they would run Too Hot (Thats why Toyota went back to the copper over the iridium plugs.) at least thats was what i was told by the toyota service tech.

I think they would run hotter than the iridums thus causing pinging and other problems with the ECU trying to match the hot plug.. possible sending more fuel making it run to rich if the plug can't keep up... or running to lean if it send the normal amount of fuel.
