Was running stock coils wires and iridium plugs for years. Had a bad coil and swithced over to Nology coils wires and silver stone plugs the difference was obvious. I don't know which part made the difference but the engine has run much cleaner for the last four years. I first swithced the coils with cut back plug electrodes and things seemed about the same then I installed the wires and the plugs cleaned up right away. I then installed the silverstone plugs with stock gap and things got better yet. A person just has to try things and not just go by reference material. I read the articles you mentioned before i bought any of the Nology items but thought what the hell it's only money and IMHO it was money well spent.
