It precisely measures the volume and density of air entering the engine, providing essential data to the engine control unit (ECU). By accurately reporting airflow, the ECU can adjust the fuel injection and ignition timing accordingly. This leads to improved combustion efficiency, reduced emissions, and optimal engine performance across various driving conditions. A faulty MAF sensor can result in poor fuel economy, rough idling, hesitation, and even engine stalling. This BOSCH MAF sensor is engineered for reliability and durability, meeting stringent quality standards. Replacing a malfunctioning sensor with this genuine BOSCH part will help restore your engine's performance and ensure smooth operation.
