Genuine BOSCH Air Pump
Part number 0580000010

An engine air pump in a car plays a crucial role in maintaining the optimal performance of the internal combustion engine. The air pump, also known as a secondary air injection pump, is responsible for injecting fresh air into the exhaust system. This process helps in reducing harmful emissions by promoting complete combustion of the fuel mixture.

When the engine is cold and during startup, the engine air pump pumps additional air into the exhaust manifold. This extra air enhances the burning of unburned fuel and further oxidizes the carbon monoxide and hydrocarbon gases in the exhaust. As a result, the air pump helps in reducing the levels of pollutants emitted from the vehicle, ensuring compliance with emission regulations and promoting a cleaner environment.
