While the use of spark plugs can be seen as early as 1800, they were not patented until 1902. In 1836, an immigrant named Edmond Berger created the first spark plug, but did not patent the idea. History credits German inventor Robert Bosch who successfully created and patented the spark plug as it is used in modern times. While electric vehicles and diesel engines do not require spark plugs, classic 4-cylinder and V6 or V8 motors still use them. There is a national Change Spark Plugs week, May 5-11, and can be traced to as early as 1929.
