This Mass Air Flow (MAF) sensor from MAGNETI MARELLI is designed to accurately measure the volume and density of air entering the engine. By providing this critical data to the engine control unit (ECU), it enables precise fuel injection and ignition timing adjustments. This ensures optimal engine performance, fuel efficiency, and reduced emissions. A faulty MAF sensor can lead to poor acceleration, stalling, increased fuel consumption, and check engine lights. Replace with a quality sensor for reliable engine operation.
