If you really want to improve a sparkplug the best way is to use a radioactive element in the electrodes. This ionizes the gases between the spark gap thus making a hotter and fatter spark. Corrosion and fouling of the plug will inhibit the effectiveness of this so it would be best combined with a platinum plug technology. Of course whether you could see a difference from tank to tank is still debatable.
