Sorry if I missed it but how many miles on the motor? I have a set of plugs and wires from Rob sitting here but removing a steel threaded plug from an aluminum head after being in there for what is likely 14 years is somewhat disconcerting. Knowing my luck I will remove most of the threads on at least one of those plugs! I have to assume no problems? I bought mine simply since I believe mine have been installed since new as I bought the car last fall with 72k miles on it so assume they are the originals. Glad it worked out for you. I have a couple of small, very small bucks at idle that I hope are removed once the new tune parts are installed! Mark
