Spark plugs play a major role in the vehicles combustion system. It is the job of the spark plug to do what they say on the tin…spark. The spark ignites the fuel/air mix to power your engine. Spark plugs come in various shapes and sizes and it is recommended that they are changed as a set rather than individually. A faulty plug could potentially be caused by a number of factors. If these are left and not changed they can potentially cause a misfire, leading to poor fuel consumption or even engine damage. In the colder months of the winter, these are likely to fail causing the vehicle to either struggle to start or not even start at all.
