Spark plugs are the starting point for combustion in your engine. They deliver the spark that ignites the mixture of air and fuel in the combustion chamber. Plus, spark plugs also transfer heat to the vehicle's cooling system. It is crucial to keep this component in good repair since failed spark plugs can result in your engine misfiring, poor performance, and reduced gas mileage. Replacing the spark plugs at the first sign of trouble can save you a lot of problems in the long run.
