Bosch 12V water pump suitable for fitting to water cooling and for racing vehicles. In racing vehicles, mechanical water pumps are often replaced with electric water pumps because they do not require power from the engine and thus more engine power is available. Also, mechanical pumps break very quickly in high revving race engines and expensive engine damage is the result.

This Bosch water pump is used by many race teams and also by many manufacturers of electric water pump kits. For the electrical connection, we recommend using the Bosch connector plug 43218. This must be ordered separately.
