Mass Air Flow Sensors

Mass air flow sensors are devices that measure the amount of air entering an engine. They play an important role in modern fuel-injected engines, as they provide vital data to the engine control unit, which in turn adjusts the fuel injection and ignition timing to optimize engine performance and reduce emissions. Mass air flow sensors work by using a hot wire or film to measure the amount of air passing over them. They are essential components in modern engines, helping to improve fuel efficiency and reduce emissions, while also ensuring the engine runs smoothly and reliably.
