The function and purpose of Spark Plug Wires.

Without the timed ignition systems in our internal combustion engines, there would be no way to generate enough power for efficient operation. The fact that your GMC Sierra 3500 HD has mechanically or electronically timed ignition means that it needs spark plug wires. The current required to detonate the air/fuel mixture effectively is transferred from your distributor or ECU in a specific order to the spark plug via your GMC Sierra 3500 HD spark plug wires. Sometimes called high tension leads, these usually have a carbon fiber core wrapped in a fiberglass barrier, and covered with EPDM rubber for insulation from the heat in your engine.

There's no reason to delay... fix it today.

Don't let a broken Spark Plug Wires bring about the demise of your car, truck, or SUV, and don't gamble with its condition by installing anything but the highest quality repair parts.
