Faced with rising fuel cost.. will a better spark plug actually helps saving?
both types have shown more firing and consistent firing and claim better engine response. Brisk even hv studies done in U of Mich.

Wat's ur POV? Worth or not worth?
Will this be too hot for most engine to handle?
Is this another snake oil?
I kinda agree most combustion r incomplete and we r merely discharging $$ as we r burning away. Otherwise iDsi engine EGR technology to recycle incomplete combustion gas would not hv proven good fuel economy overall performance. So for other cases, a better plug to compensate this difference?
Anyone uses them before can share ur view?
