The function and purpose of Spark Plug Wires.

Without the timed ignition systems in our internal combustion engines, our engines would have to be all electric. The fact that your GMC PM251 has spark plugs wires means that it is either mechanically or electronically timed. The voltage necessary 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 PM251 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.

The best parts are right around the corner.
