Spark Plugs

When you turn the key or press the ignition button, you expect the engine to crank. That requires a lot of components doing their jobs perfectly. The battery needs to send electricity through the spark plug wires to the spark plugs, which generate the spark necessary to combust fuel and oxygen and turn the engine over. If your spark plugs are old and worn, there's a chance that they are not doing their job properly. Signs of aging, worn out spark plugs include sputtering while running, rough idling, lost fuel economy, and more. Replacing your spark plugs is part of regular maintenance and should be done based on the schedule your automaker specifies. In addition to changing them at the right time, though, you also need to make sure that you choose the right spark plugs. This goes well beyond ensuring that they're sized to fit your engine and gapped correctly, though. You should opt for genuine OEM-quality spark plugs, rather than generic aftermarket plugs.
