The BREMI 30213 Mass Air Flow (MAF) Sensor is engineered to precisely measure the amount of air entering your engine. This critical data allows the engine control unit (ECU) to calculate the correct amount of fuel to inject, ensuring optimal combustion. By providing accurate airflow readings, this sensor helps maintain ideal engine performance, improve fuel economy, and reduce harmful emissions. A malfunctioning MAF sensor can lead to poor acceleration, rough idling, increased fuel consumption, and check engine lights. This BREMI MAF sensor is built to meet or exceed original equipment specifications, offering reliable and consistent performance. Installation is straightforward, making it a direct replacement for your vehicle's original sensor.
