This PIERBURG Mass Air Flow (MAF) sensor, part number 7.22184.17.0, is engineered to accurately measure the volume and density of air entering your vehicle's engine. Accurate air intake measurement is fundamental for the engine control unit (ECU) to calculate the correct amount of fuel to inject. This precise calculation ensures optimal combustion, leading to improved engine performance, fuel efficiency, and reduced emissions. Replacing a faulty MAF sensor can resolve issues such as rough idling, poor acceleration, engine stalling, and illuminated check engine lights.
