How to Install Spark Plug Wires on a 2000 Dodge Durango
Spark plug wires wear down in time, and breaks in the wire or other damage may occur. When damaged, the wires are unable to send the electrical current to the spark plug needed to create the spark that ignites the fuel in your engine. This can lead to misfires or other performance issues with your engine. You can return your 2000 Dodge Durango's engine to regular performance by changing the spark plug wires every 30,000-50,000 miles or sooner if the wires are damaged.
