My take on plug wires as taught by my Porsche mentor was as follows: stock engine, use stock or factory wires as my daughter's 914 2L. If modified such as my race car was with a MSD box, high voltage off road coil then use 9mm racing wires and replace yearly. I bought a 100 foot roll of 9mm wire, generic ends (both plug and distributor and made my own, usually over the summer break (San Diego you know). I had a MSD spark voltage tester and when new the voltage at the plug was about 15,000 volts and after a year would fall off to 12000 volts or so due to the heat, etc.

Summit Racing sell various colors so I had blue to match my car.......
