Your Ford Ranger spark plug wires are a vital part of your vehicle’s ignition system. As you may know, the ignition system sends the spark to your combustion system that allows the oxygen and fuel mixture inside your cylinders to burn, which produces power that starts your engine and keeps it running. Your Ranger spark plug wires convey massive amounts of electricity from your rotor to your spark plugs several times per minute in order to produce spark.

Since the wires handle tens of thousands of volts at a time, they have to be in good shape. If the wire coating of your Ford Ranger spark plug wires is cracked or damaged, the electricity has a path to escape, and this loss of power will result in lowered fuel efficiency, sluggish engine running, engine misfires, and detonations.

Your spark plugs will also quickly become fouled when the wires are damaged, making them unable to deliver a healthy spark. Checking your Ranger spark plug wires periodically for damage is a good idea, but you will not always be able to see cracks in the underside of the jacket or damage to the wires inside. You should plan to change your Ford Ranger spark plug wires every time you change your spark plugs, as well as with every engine tune-up. New spark plug wires are not expensive, they are easy to install, and they can make a big difference in the performance of your engine. You may even want to consider installing high performance Ranger spark plug wires, that feature a thicker silicon jacket to produce a hotter spark.Find the set of spark plug wires you need in our extensive online catalogue, and enjoy our deep discount prices and fast, reliable shipping.
