The Air Mass Sensor measures the amount of air entering the engine so that the engine control module can determine the amount of fuel to inject. This ensures the most efficient air/fuel mixture for the best fuel economy and power, while reducing harmful exhaust emissions. Remanufacturing the mass air flow sensor is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear and failure with new components. Damaged and obsolete parts are replaced and are 100% end of line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing also benefits the environment by returning components back into service rather than processing as scrap or simply disposing of them. This Air Mass Sensor is manufactured to fit your specific GM vehicle and will provide the same performance, durability, and service life you expect from ACDelco.

Product Features:

Measure the amount of air entering the engine so that the engine control module can determine the amount of fuel to inject
Undergo the same stringent testing process as the original part
Offering the quality, reliability, and durability of OE
