The MEAT & DORIA Mass Air Flow (MAF) Sensor, part number 86146E, is engineered to accurately measure the amount of air entering the engine's intake manifold. This critical data is then sent to the engine control unit (ECU) to optimize 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, poor acceleration, increased fuel consumption, and illuminated check engine lights. MEAT & DORIA is committed to providing reliable and high-quality components. This MAF sensor is designed to meet or exceed original equipment specifications, ensuring a proper fit and function for your vehicle.
