Spark Plug Wire Sets

The electrical systems in a vehicle really take a beating. They are in use all the time. Spark plugs and wires are components of a vehicle that need to be replaced more frequently than many other parts. About every 20,000 miles the spark plugs and wires should be replaced. The wires can be purchased in sets. Spark plug wire sets are just like many other auto parts, they need to be purchased for the make and model exactly. If substitutions are made, the engine may fire incorrectly. Spark plug and wire replacement is a job that can be accomplished by many amateurs with little problem. The trick is to make sure they are done one at a time or the wires may get mixed up. If wires are placed incorrectly, it can cause the engine to run extremely roughly. This is because the wire placement determines the order the sparks fire.
