Jaxonalden - Aren't the Bosch FGR 6 KQE and FGR 6 KQC plugs four electrode? Since dual is better than single, is it safe to assume that four is better than dual? It's starting to seem like the Bosch Copper plug is the way to go?

Does anyone know if the OEM Beru plugs are Copper or Platinum?

So, from what I've learned so far...

Copper is better than Platinum because the Platinum tips can break off into the cylinders. And, Iridium is better than Platinum because it is harder and will last longer. So, is Iridium also better than Copper, or does Copper have its advantages too?
