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. A properly functioning 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, poor acceleration, increased fuel consumption, and check engine lights. This MAGNETI MARELLI MAF sensor is engineered to meet or exceed original equipment specifications, ensuring reliable and consistent performance. It is a direct replacement for your vehicle's original component, facilitating a straightforward installation process.
