1985 Ford F-150 - Spark Plug Wires

Ford F-Series Spark Plug Wire Set

The spark plug wires for your Ford F-Series transfer power from the coil and distributor to the spark plug. These wires have a boot on each end and an insulated core that carries the current. With time, the spark plug wires or boots can become damaged by heat and wear out. If one or more of the cylinders on your Ford aren't getting a spark, this could be a problem with the spark plug wire. Whenever you change the spark plugs, it's a good idea to change the spark plug wires for a complete tune-up and better performance. Signs that your Ford F-Series truck may need spark plug wires include misfiring, an erratic idle, increased emissions, or a Check Engine light that is on. A new set of spark plugs and spark plug wires can also help improve fuel economy and performance. If your Ford truck needs spark plug wires or other tune-up parts, O'Reilly Auto Parts has what you need to keep your truck running at its best.
