This Mass Air Flow (MAF) sensor from BOSCH is designed to accurately measure the volume and density of air entering the engine. By precisely calculating airflow, the engine control unit (ECU) can determine the correct amount of fuel to inject for efficient combustion. A faulty MAF sensor can lead to various drivability issues, including poor acceleration, rough idling, increased fuel consumption, and illuminated check engine lights. Replacing a worn or malfunctioning sensor with this high-quality BOSCH unit helps restore engine performance and fuel economy. Engineered to meet stringent OEM specifications, this sensor ensures reliable and consistent readings, contributing to the overall health and longevity of your engine. It is a direct fit for specified applications, simplifying the replacement process.
