Bosch manufactured its ten billionth spark plug. The landmark plug was made at the company’s Bamberg plant in Germany, which was opened in 1939 and has manufactured the majority of the company’s output. Laid end-to-end, the Bosch spark plugs that have been made would form a chain stretching for more than 348,000 miles, circling the equator approximately 14 times.
