platinums are good for longevity. if you want max performance, just swap copper plugs out every 6mts or so. oh, the zfr that you mentioned are copper

Platinums on a FI car are not good if you plan on pulling the plugs and using them as a tuning aid. The platinum plugs are self-cleaning so they don't show if your car is rich or lean.
