Recently I've been reading that the Copper plugs (the cheapest ones available) are an upgrade for those who are willing to change their plugs more often. Please see the link below
Apparently, the copper conducts the spark far better than Iridium, better performance and fuel economy improvements. It's downsides are it's lifespan is a fraction of the Iridium.

Has anyone tried going to Copper plugs? I honestly don't mind changing them out once a year, considering their low cost.
Anyone done this "upgrade" before?
thanks in advance
