When your GMC C25 was born, it was destined for a person with discerning taste who values longevity in their automobile.

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 C25 has mechanically or electronically timed ignition means that it needs spark plug wires. The current required to ignite the air/fuel mixture in your combustion chamber is transferred from the engine control module (on newer vehicles) or distributor (on older vehicles) to the spark plug via your GMC C25 spark plug wires. Sometimes called high tension leads, 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.

You've tried the rest, now try the best.
