Car aficionados appreciate the strong looks built into each GMC, and know that only the highest quality repair S15 parts will suffice when repairs are needed.

What Spark Plug Wires does for your vehicle.

Without the properly working ignition timing system developed for the internal combustion engine, there would be no way to generate enough power for efficient operation. The fact that your GMC S15 has mechanically or electronically timed ignition means that it needs spark plug wires. The voltage necessary to detonate the air/fuel mixture effectively is transferred from the engine control module (on newer vehicles) or distributor (on older vehicles) to the spark plug via your GMC S15 spark plug wires. Sometimes called lead wires, they consist of a carbon fiber core to conduct the current, a fiberglass barrier to protect against RFI and EMI, and rubber or silicone on the outside for insulation from the heat in your engine.

CPD has what you need.
