I'd like to see an actual back to back to back dyno comparing copper to iridium to platinum in a normal car. Most tech articles I've read say copper is the best for engines like ours, but some say iridiums are - who knows? It's all theory one way or the other.
I bet it's all marketing and they just changed the box.....
Iridium fits well on the periodic table so I figure it must be good, right? I'm a metallurgist but I don't ever recall studing the conductive effects of Ir?
Like I said I would have purchased Plats but they were out. It runs the same so I figure it can't be too bad, I change them in 40k anyway.
I'm holding out for the never needs changed NGK's made from Unobtanium.
