This Air Mass Flow (MAF) sensor from MAGNETI MARELLI is designed to accurately measure the volume and density of air entering your engine. By providing this critical data to the engine control unit (ECU), it allows for 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 rough idling, poor acceleration, increased fuel consumption, and check engine lights. Manufactured to meet stringent quality standards, this sensor offers reliable and consistent performance. It is a direct replacement for the original part, ensuring compatibility and ease of installation.
