Spark plugs are the part of an ignition system in your vehicle that helps to send electricity to an air and fuel mixture. This helps produce the necessary spark needed for the combustion process to take place and your engine to start. There can be a range of issues that occur due to faulty spark plugs, like incomplete combustion or misfiring. Replacing spark plugs should be a top priority if you notice any of these problems occuring.
