Re: NGK copper or NGK iridium? (ForceThis!)
get the coppers if you don't mind changing your plugs every 20k. if your lazy and rather do it every 50k then get the iridiums. also if you have a V6 i would suggest the iridiums since changing the 3 plugs in the back are not easy and i think you would rather do that less frequently.
