ACDelco Gold remanufactured mass airflow sensors are high-quality replacements for many vehicles on the road today. A key part of the engine management system, MAF sensors measure 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 with new components. Damaged and obsolete parts are replaced and are end-of-line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing returns components back into service rather than processing as scrap or simply disposing of them. Order the sensor recommended for your vehicle.
