Just out of curiosity, where did you get your EE degree?
Running a wider gap on a plug ... ANY plug, means that you have to develop more voltage to jump that gap. Add compression and the amount of voltage required jumps even higher. The higher the voltage required to jump that gap, the higher the secondary voltage will be on the mag COIL. The higher the voltage is in the secondary of the mag COIL, the more easy it is to have insulation breakdown and failure occur. That's why true racing systems develop voltages upwards of 40 to 50 THOUSAND volts and don't break down when operated at that voltage level. Increasing spark plug gap will NOT lead to longer mag coil life. Even assuming the wire resistance is a tad better or worse than the next guy.
A wider gap does indeed give a stronger spark and does indeed lead to better ignition of the fuel mixture. It also requires a higher voltage. Lower wire resistance increases current flow. Total voltage is still increased with a wider gap, and your statement about these features extending coil life are arbitrary and without basis other than pure conjecture and are factually incorrect. The laws of physics still apply.
A very simple check would be to test the coil temp with different designs. The inherent hysteresious loss of any coil will cause a temperature increase with a higher voltage and current demand. If the temperature of the coil is decreased with your system at least you would have some science involved with your statements.

Gang,
One of the things I have neglected to mention previously is the concept of total resistance - one of the biggest concerns of this discussion. Our system, developed over a couple years by friends of WW working closely with gurus in high energy electronic ignition systems, provides the lowest total resistance of any upgraded ignition system for our engines that we are aware of. In addition to the other benefits previously described, one of the biggest reasons for the Iridium plugs is it allows us to run a wider gap and, using our ultra low resistance 8.5mm wire, and still have lower resistance than the other systems out there, which makes the coils last longer.
Now, when an electronic system is developed, that will be the ticket....
Hope this helps,
Barry
