Wires, 8 cyl GM Custom Fit

Now you can get a “stock-look” spark plug wire, that performs! We’ve designed our 7mm wires with the same core we use in our 8mm wire. The only difference is the 7mm flat black silicone jacket that hides its performance potential from the naked eye. Get the best of both worlds with state-of-the-art performance and a “stock look.” These wires will fit most original wire looms. Select a custom tailored set for a great out of the box fit or a universal kit to match your unique engine and wire loom configuration.
