GMC K25 Spark Plug Wires

Keeping your K25 in top shape is your top priority.

While it may not be difficult to find replacement parts for GMC vehicles, these days only the highest quality are required to repair your car or truck. You bought your K25 because its dependability and trusted quality struck a chord inside you; so why would you settle for second best when it comes to superior quality auto parts? Anyone who operates a GMC knows that when it comes to repairing their vehicle only the most superior replacement parts will do. The vehicle in your driveway symbolizes the best in class compared to all the other vehicles in today's marketplace.

Don't go too long without fixing your Spark Plug Wires... here's why.

Without the properly working ignition timing system developed for the internal combustion engine, we would need an alternative like the turbine engines we find in jets. The fact that your GMC K25 has spark plugs wires means that it is either mechanically or electronically timed. 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 K25 spark plug wires. Sometimes called ignition wires, these usually have a carbon fiber core wrapped in a fiberglass barrier, and covered with EPDM rubber for insulation from the heat in your engine.

We've got what you are looking for.
