has any one used the the msd super conducter 8.5mm plug wires on a 3.1 L 96 lumina, is it worth the extra money, or will mess with the ecm cause of the lower ohms

Or a big waste of money if it isn't modded in anyway because the stock wires work perfectly fine. Seriously, you will benefit from nothing by upgrading the ignition system if you haven't done any internal work.
