Select Your VehicleThe vehicle in your driveway is head and shoulders above the rest when it comes to all the vehicles these days. When your GMC P25 left the factory, it was destined for a person with discerning taste who wants longevity in their automobile. You bought your P25 because its dependability and trusted quality agreed with your nature; so why would you be okay with second best when it comes to superior quality auto parts? Your GMC dealership isn't the only place to locate the highest quality replacement parts for your P25.

What Spark Plug Wires does for your vehicle.

Without the timed ignition systems in our internal combustion engines, our engines would have to be all electric. The fact that your GMC P25 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 P25 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.

We've got all the top brands.

Trust in the value of the parts you get from carpartsdiscount.com and save time and money on all your upcoming repairs.
