Here’s a fact for the day: Bosch has just made its ten billionth spark plug.
The anniversary 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 would form a chain stretching for more than 560,000 kilometres, circling the equator approximately 14 times.
