BOSCH Pack of 4 Nickel Spark Plug (0242235951)

The function of the spark plug is to create an electric spark which ignites the compressed air-fuel mixture in an engine cylinder. It must permit reliable starting, guarantee that there is no misfiring and operate during extreme conditions. For 100 years, Bosch Spark Plugs have been designed for optimal performance, reliable functioning and to withstand extreme operating conditions. Today, spark plugs are a key engine system component. They play a major role in fuel economy, efficient combustion and reliable operation of engines and catalytic converters. In the course of its service life, the spark plug undergoes changes that increase its required ignition voltage, eventually leading to engine misfires. These changes can be caused by electrode wear, engine wear and abnormal operating conditions. Independent tests have shown that installing Bosch spark plugs can reduce voltage demands by 24%, leading to a longer spark plug life.
Bosch Spark Plugs meet or exceed OE requirements of all vehicle and engine manufacturers when properly installed in accordance with the recommended application.
