Anybody familiar with Iridium spark plugs? How important is it to use them if the owners manual specifies them? What are the benefits?
and they require less voltage to produce a spark.
... they require less voltage to produce a spark.
What law of physics comes into play to achieve that feat?
The spark jumps an air gap - the air gap is what determines the voltage requirement.
Sure, lower resistance in the materials would reduce the voltage lost before reaching that gap, but compared to the run of wire, and the built in resistor that is in most plugs, the resistance of the tip material is going to be miniscule, probably micro or nano-scule (if that's a word).
At any rate, copper conduct more than 2X better than Iridium, so not even that would explain it. Iridium may last longer, and if the manual specs it, I'd go with it. But I wouldn't expect it to affect the voltage required to produce a spark.

From the article:
"Reasoning that it was an engine-management or ignition-system problem, he replaced both."
"Kenny had correctly diagnosed the problem, but as far as he knew, there was no solution. He was already using the most powerful engine management and ignition systems on the planet, "
Edit Add: In the trade this called "shotgunning" the problem, hoping, praying, maybe....
Ah, what brilliant analysis, splendid troubleshooting skills. This guy is pro!!!!. The worst tech I ever had could do better in his sleep.
Nowhere do they show dyno curves. No voltage graph. It is nothing but a very thinly veiled hype for iridium plugs.
The article is not worth the paper it was written on.
