This PIERBURG Mass Air Flow (MAF) sensor, part number 7.22184.74.0, is engineered to precisely measure the volume and density of air entering your vehicle's engine. This critical data is then sent to the engine control unit (ECU) to calculate the correct amount of fuel to inject for optimal combustion. By ensuring the ECU has accurate airflow readings, this MAF sensor helps maintain consistent engine performance, improve fuel economy, and reduce harmful exhaust emissions. A malfunctioning MAF sensor can lead to poor acceleration, rough idling, increased fuel consumption, and check engine lights. PIERBURG is a trusted brand known for its high-quality engine management components. This sensor is designed to meet or exceed original equipment specifications, providing a reliable solution for your vehicle's air intake system.
