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. This original equipment mass air flow sensor has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

SENSOR IS NOT A GENUINE GM SENSOR. Did not work and threw a check engine light code after 5 minutes of driving

This mess airflow sensor arrived on time in well protected package and was packaged in original GM packaging. Had to replace on my 2018 GMC 2500 HD Dinali 6.6 diesel just due to a lot of particulate matter from multiple wildfires in 2021. Item was easy to install and it still uses the original screws that are on the old module. One thing I recommend is utilizing mass airflow cleaner each time you change your air filter or at least every 10,000 miles.
