This Mass Air Flow (MAF) sensor from MAGNETI MARELLI is designed to accurately measure the volume and density of air entering the engine's intake system. By providing this critical data to the engine control unit (ECU), it enables precise adjustments to the fuel injection and ignition timing. Proper functioning of the MAF sensor is essential for maintaining optimal engine performance, fuel efficiency, and reducing emissions. A faulty sensor can lead to various drivability issues, including rough idling, hesitation, poor acceleration, and increased fuel consumption. Manufactured to meet stringent quality standards, this sensor offers reliable and consistent performance. It is a direct fit replacement for the original part, ensuring compatibility and ease of installation.
