ACDelco GM Original Equipment Mass Air Flow (MAF) Sensors are key parts of the engine management system, and are GM-recommended replacements for your vehicle's original components. The MAF sensor measures the amount of air entering the engine so that the engine control module can determine the amount of fuel to inject. This helps ensure the most efficient air/fuel mixture for the best fuel economy and power. These original equipment mass air flow sensors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
