Genuine Bosch Spark Plug FR8DC

A spark plug in a car is an essential component of the ignition system. Its main function is to produce a spark that ignites the air-fuel mixture within the combustion chamber. This spark is created by an electrical current that is sent through the spark plug from the ignition coil. As the current flows through the plug, it jumps across the spark gap, generating a high voltage spark. This spark ignites the compressed air-fuel mixture, initiating the combustion process that powers the engine.

Furthermore, a spark plug also plays a crucial role in heat dissipation within the combustion chamber. It is designed with a metal shell and a ceramic insulator that separates the center electrode from the shell. This insulator helps to keep the high heat generated during combustion away from the spark plug's metal components, preventing overheating and potential damage. Additionally, the design of the spark plug's electrode determines its heat range, which affects its ability to dissipate heat. Overall, the spark plug ensures efficient combustion and reliable engine performance by providing the necessary spark and heat management within the combustion chamber.
