I switched the original platinum plugs out with the AC DELCO iridium plugs and changed my cables to the AC delco red performance ignition wires. I have been running the same plugs for well over a decade and the cables for over 5 years without any issues. Fuel economy on long highway drives is somewhere around 7L / 100km. The red cables are much better quality than the original black ones on my 2003 C5 convertible. I have tried other aftermarket perfomance cables but they seldom fit properly and the resistance of the AC delco wires is better matched to the impedance of the OEM ignition coils.
