The PIERBURG Mass Air Flow (MAF) Sensor, part number 7.22184.26.0, is engineered to precisely measure the volume and density of air entering your vehicle's engine. This critical data is then transmitted to the engine control unit (ECU) to calculate the correct amount of fuel to inject, ensuring efficient combustion. A properly functioning MAF sensor is vital for maintaining optimal engine performance, fuel economy, and emissions control. When this sensor degrades or fails, it can lead to a range of issues, including rough idling, poor acceleration, increased fuel consumption, and illuminated check engine lights. This PIERBURG MAF sensor is designed to meet or exceed original equipment specifications, providing a reliable and accurate measurement of airflow. Its direct-fit design ensures straightforward installation, replacing your old or faulty sensor with a high-quality component that restores your engine's performance and efficiency.
