well I have the famous high end miss....even with moroso plug and coil wires and an MSD coil. My first step is coil wire, then coil, then plugs, then plug wires, then opti. I am hoping the coil wire fixes it. Anyways, should I just get a GM coil wire?

 

I'm running a Jacobs Coil and Coil wire. It is still good. I had the MSDs but after a year they were already brittle.
