There are a lot of different components in your engine's ignition system. The ignition system has nothing to do with starting your car; rather, it is designed to generate and carry the spark that ignites the fuel within the cylinder. It is an incredibly precise and complex system, and it is very important to keep it in good repair. As in any electrical system, a small problem anywhere in your engine's ignition system will affect the functionality of the entire thing. That is why every part of the system from the battery to the plugs needs to be in good shape.
