Hella 358166231 Remanufactured Mass Air Flow Sensor (MAF) 4-Pin Bolt-On

The Hella 358166231 is a remanufactured mass air flow (MAF) sensor featuring a 4-pin connector and bolt-on flange/pipe-neck attachment method. It includes the complete housing and is engineered to restore accurate airflow measurement to the engine management system.

The mass air flow sensor measures the volume and mass of air entering the engine intake. This data is transmitted to the engine control module (ECM), which uses it to calculate the precise fuel delivery needed to maintain the correct air-fuel mixture. A failed or degraded MAF sensor can result in excessively rich or lean fuel mixtures, leading to drivability problems.
