Review on πŸ” 213-4527 GM Genuine Parts Mass Airflow Sensor Kit with Wiring Connector - Optimize Your Search by Trevor Rodke

Revainrating 5 out of 5

Instead of using aftermarket junk, return an AC Delco factory part to your GM vehicle.

Purchased used Buick Rendezvous was equipped with a non-original mass air flow sensor. An aftermarket mass air flow sensor with a low reading of the amount of air entering the engine, causing the fuel trim to shut off and using more gas than it should. A new ACDelco MAF sensor was ordered and is now reporting the correct amount of air entering the engine. Car runs fine, gas mileage is much better now, don't use aftermarket mass air flow sensors. your garbage. Install a factory AC Delco MAF sensor in your GM vehicle.

Pros
  • Excellent overall performance
Cons
  • Some defects
