Spark plug wear is often overlooked and they are only replaced when starting issues or engine misfiring occur. Instead, spark plugs should be replaced periodically as per the maintenance schedule since electrode wear compromises the quality of combustion and thus the engine's efficiency, affecting both performance and fuel consumption.

Additionally, this maintenance task is quite economical and can easily be performed as a DIY project with a simple spark plug socket.
