Props to you on the seamless topic transition to a "What oil am I running?" thread!
*raises hand*
My bad!
Anybody tried the E3 Spark Plugs?

0.100 of what?
MV? Calorie/Second? Dyne? Therm?
I won't pretend to know what the perfect combustion scenario is, but I do have a Engine Development PhD for my V.P. of Engineering and an Engine Development Engineer for a supervisor whom I could ask.
My point is and was that if the spark is good enough to get the fuel mixture lit in any reasonably possible operating scenario then anything beyond that is money spent for not much gain. The lone exception would be if the money spent resulted in better reliability. The stock system with normal plugs seems to work pretty well. Were we talking massive boost or lots of NOx or some other method of increasing the A/F density in the combustion chamber, then more potent ignition systems are worth looking into.

So i ended up gettin NGK v-power plugs
That would be inchs. Because your an engineer, I'll brake it down for you! Most folks in the U.S. gap there plugs in inch's .1, .10 and .100 are the same.
Most plugs call for .028"~.055" but an ideal plug gap would be .100"
To archive such a gap, one would need a very very large coil.
I've done dozens of high capacity coil upgrades on older cars, and the difference was night and day. Much better cold starts and notably better MPG.
I'm just here to help and be helped. If you don't believe my post? than don't take my advise.

How long do your plug wires, cap and rotor last with that kind of spark plug gap?
Was the night and day difference between a worn and tired ignition system and the new set-up, or between a well running ignition system and the new set-up?

They were 70's Volvo's and Toyota's. There systems were in good order. I just changed the coils and plugs, increasing the gap to .055
My 85 PU has been running .055 gap for about 10 years @ 200K miles. I cant remember the last time I changed the plugs, wires, cap or rotor. These components have well over 100k miles on them.
The truck has 425k miles and is being junked this week.

I wonder what you're doing differently from everyone else who has gone down this path? In all of the trials that I've seen it worked for a while, but nowhere near 100k miles.
A lot of details in that statement.
