Nology has been known to make some gimmicky ignition products, so I'm very skeptical of anything ignition-related that comes from them.
The conductivity of the metal is one of the lesser important features of a spark plug. If you read our Spark Plugs Article
you'll see alot of different things that affect how a spark plug performs that Nology seems to think they can throw out the window just because silver is a better conductor. If we look at the conductivity of the other metals, we see a discrepancy.
Zinc == 1.16
Aluminum == 2.37
Copper == 4.01
Steel == 0.70 - 0.82
Platinum == 0.716
Iridium == 1.47
So copper is obviously the best thermal conductor out of this list, 3x more than iridium. Does that mean a copper plug will outperform an iridium plug by 3x? No way. What about platinum? They look to be the worst on this list yet platinum plugs are preferred in alot of cases and will perform.
This quote from the article was rather interesting.

So I'm inclined to think this silver plug stuff is just a gimmick. I don't know the specific thermal conductivity of silver, but if it is a little more than copper, I can't see why it would make any difference when there are many other factors that go into making a good spark plug. Nology though seems to think none of these things are important and went ahead to make a poorly designed electrode and put silver on it.
I completely lose all respect for Nology's product with this little paragraph they have on their new plugs.
Quote: from Nology STOP playing around with spark plugs that feature fine wire electrodes, split electrodes, ring electrodes, multiple electrodes, platinum electrodes, copper electrodes, or gold electrodes, and get serious with silver electrodes! Silver is the best electrical and thermal conductor of any metal. This makes SilverstoneEthe best spark plugs in the world. Period!
Smells like BS to me.
