8 mm spark plug wires

I need to replace the stock 7mm spark plug wires. Will there be any issues with larger wires on a stock GM opti ? THANKS !

no issues with the opti. only thing you may run into is the bigger wires are a pain to get into the looms.

Not at all, just drill them out and file down the rough edges -- problem solved w/8.5mm MSD wires! ;-)
