Hi Scott / qlist, I read your comments on the regular plats experiencing ceramic insulator breakdown, and I wondered, is this pretty much just a turbo app problem? What's your opinion on using them in a NA engine (like our '86 5kS)? I've been using 'em in my '79 Fox for many years with no probs. TIA! Karl K. '86 5OOOS 136k mi Mesa, AZ '79 Fox 146k mi
