Review on Cardone 74 50055 Remanufactured Airflow Sensor by Derick Johns

Item arrived dirty (MAFs should be clean as they are always behind the air filter) indicating the effort put into the rebuild. Also, they used sealant that was too harsh where they separated and glued the part. Too much sealant will falsify the mass air flow reading as some of it was in the test port where the mass air flow wire is located. Given that this product has been carelessly redesigned, I'd say spend a few bucks more and get a new OEM MAF. This saves you the headache of wondering if your fuel trim is off due to poor MAF readings.
