will using copper plugs decrease/harm performance??
I ask because since our cars came with platinum plugs, would replacing it to copper (for Nitrous use) harm the performance or components in the car when not using the bottle? Does anyone know? Nitrous users please help

Copper plugs are generally better for performance. But, as I am sure you are aware, they do not last as long. If you are running nitrous with copper plugs, just try to change them every 15k - 20k miles (24k - 32k kilometers for you.

The idea is that the Iridium conducts nearly as well as the copper but last longer.
Gap the plugs at the factory spec. If you are having some firing issues with the nitrous you could run a sligthly smaller gap. But I would not expect any firing issues.
