Buy the Magnacore wires and pay $100 once (IIRC SP has them on special)
Never have to change them out but it's free if you have too.
...or...
Pay $40 for the FMS and change them every year or two.
...or I suppose...
Spend $60 on the Autolite Pro/Bosch Pro once (good reviews to date) and live with the "not fancy" color.
Change them out every 3-4 years but it's free. (lifetime warranty like the Magnacores)
