Spark plug wires are one of the most important pieces of the Ignition System. You can have the best ignition control and coil possible, but if the plug wires aren't to snuff, all the energy will just be wasted.

Not only do plug wires need to carry extremely high voltages, but they have to do it in harse enviroment. MSD wires must be able to handle extreme heat, abrasion, and even getting whipped around from racing speeds. Also, the crimps and connections must be secure and live up to being pulled off in the pits during tune-up sessions.

MSD offers two different spark plug wires that meet and exceed these requirements!
