This Mass Air Flow (MAF) sensor from CONTINENTAL/VDO is designed to accurately measure the volume and density of air entering your vehicle's engine. 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 engine efficiency, reducing emissions, and ensuring smooth acceleration. A faulty sensor can lead to poor fuel economy, rough idling, engine misfires, and the illumination of the check engine light. Ensure your engine receives the correct air-fuel ratio for peak performance and longevity with this high-quality replacement part. It is engineered to meet or exceed original equipment specifications for a reliable fit and function.
