just stay with ol copper plug, ngk
Copper plugs naturally have a short life, my car was completely debilitated coming home from the beach one night with under 7K on the plugs. Never again.
I would only buy if they have the long threaded versions. Not looking to shoot a plug through my heads.

I bet 80% of us here using copper.
I don't think it would be that high. The newer 4.6s come from the factory with platinum plugs.
