i know everyone is asking about sparkplugs lately. all im wondering is what is the difference between the champion golds, platinums, double platinums and the copper plus plugs. i was checking Napas site for my CV shafts and looked up the plugs and it had those different types. i was just wondering the differences between them.

Platinums bad, my 3.5L ate them up. I had to change them in a year with less than 15,000 miles.

Yep, Champion RC12LYC plugs are what DC ended up putting in ‘97 models at the factory. FWIW, I’d personally recommend those or the Champion Gold 2412 plugs.
