An ACDelco Professional Remanufactured Mass Air Flow (MAF) Sensor is a high quality replacement for many vehicles on the road today. It is a key part of the engine management system. 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 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. This mass air flow sensor will provide the same performance, durability, and service life you expect from ACDelco. ? WARNING: Cancer and Reproductive Harm -
