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 crucial 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, stalling, and decreased power. Manufactured to meet stringent quality standards, this sensor ensures reliable and consistent performance. It is a direct replacement for the original part, facilitating an easy installation process.
