I don't think I ever change mine. I would like to know as well.
Also, correct me if I'm wrong anyone, Aftermarket plugs are not better than OEM right? they're about the same?
And the Plug Wires, which brand is the best? NGK?
Sorry Adam9981, I didn't mean to be an a** and jack ya thread, Hopefully that these questions would benefit you as well. Again, sorry. Also WELCOME TO THE BOARD AND HAVE FUN...........:thumbup:
