Ive used MSD wires, FMS wires, and Livewires.
The livewires are the best looking without a doubt. I have already ruined one wire though, and ive had them on for 1 week. The inside clamp stayed on the plug when i pulled the wire off.
Ive killed a tun of MSD wires as well, i dont care for them since they use a straight spark plug boot.
The only wires that held up was the FMS wires i had, but i changed to the livewires for the look.
