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.
Well conductivity-wise, copper is the best by quite a bit, with iridium in second...c'mon, this stuff is almost on the periodic table
But at least in my plant, metallurgists never deal with that crap. Anyway, some say it has more to do with electrode size and positioning than conductivity. I change my coppers every 30k and they cost like $2.40 apiece, so I really don't think it makes that big of a difference as long as you maintain your car well.
