Stock sucked I tried FRPP 9mm wires twice and didn't like them. The plastic distributor boots broke within a year. I've had MSD Superconductors now for over 4 years but am getting a code off of one of my cylinders and my plugs and injectors are new so I think it's the wires. I'm thinking of giving the Taylors a shot cause I've heard MSD are the same as FRPP or whatever they are called these days. Gonna order soon so speak up...! Don't need anything bigger than a 9mm. If you have opinions please... post it up.
