How long do MSD spark plug wires last? I installed the 8.5mm MSD spark plug wires on my GTA about 10 years ago. I've also put about 100K or more miles on them. All marketing BS aside, how long will these really last? They still look like new so I guess in my mind it's hard to trash them and install a new set... |
