Hot Film MAF Sensor
Similar to the hot wire type, this design uses a flat thin-film resistor element instead of a wire. It operates on the same principle of temperature change to measure air mass, offering greater durability and reliability. Hot film MAF sensors are widely used in modern vehicles.
Hot Film MAF sensor — uses a durable thin-film resistor element instead of a wire. The orange gasket seals the sensing module within the intake housing.
