In order to comply with the vehicle emission limits demanded by law, it is necessary to maintain a given air/fuel ration exactly. This requires sensors which precisely register the actual air-mass flow and output a corresponding electrical signal. Bosch air mass sensors are built to exacting specifications as required for such a sensitive measuring device. Long recognized as an industry leader in ignition and fuel systems, Bosch's quality, innovation, and experience are the foundation of the entire line of engine management components.
