About Plug Cables
The plug cables are important in igniting the fuel and the available air in the combustion chamber to facilitate the movement of the vehicle.
Plug cables in a car are not meant to give service for the longest time of a car’s lifetime. These cables should be replaced when they are worn out. High temperatures cause this part to wear out and affect its effectiveness. The plugs should also be replaced for every 30,000 miles. They show signs of needing to be replaced with either cracks or nicks. Car hard starts are also indications of malfunctioning plug cables.
