Are you having a hard time getting your Ford F-100 truck to start? It might be the spark plug wires that are the culprit. Your ignition system creates voltage from the battery to ignite your engine, and it is up to the spark plug wires to transport that charge from the distributor or ignition coil to the spark plugs.

Over time, this high-volume of electricity and enduring hot temperatures can take its toll on your spark plug wires, leading to decreased reliability and other issues. If your F-100 spark plug wires have seen better days, or if you’re replacing your spark plugs, check out replacement wires. Don’t forget to keep your wires organized with spark plug dividers and separators as well.
