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 C25 has spark plugs wires means that it is either mechanically or electronically timed. The voltage necessary 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.

High quality parts, prices that won't break your bank, knowledgeable professionals.
