Spark plugs simply deliver current from the ignition system to the combustion chamber of the spark-ignition engine. Although spark plugs are inexpensive to buy anyway, some still opt to go for cheaper options. And well, that results in the spark plugs wearing out even sooner which we all know means that they need to be replaced often to. Investing in some good quality spark plugs will save your hours of your time and hundreds of dollars in the long run. A spark plug replacement must be made only if the new spark plug being installed is of high quality. Using poor quality accessories and equipment in your car will lower its performance and damage it severely. Spark plugs are used to measure ionization in the cylinders as well. When they are used as in other applications such as furnaces they are sometimes referred to as flame igniters.
