Bosch remanufactured air mass sensors are rebuilt using all new internal parts that are engineered to exacting specifications as required for such a sensitive measuring device. Through a precise manufacturing process, the correct type and thickness of platinum wire or thick film ceramic measuring elements are selected and accurately calibrated to provide optimum performance. Product Features:OEM Quality Direct fit ApplicationRemanufactured using all new internal partsMeasurement of air mass (gas mass) through-flow per unit of time, independent of density and temperatureExtensive measuring rangeHighly sensitive, particularly for small changes in flow rateWear-free since there are no moving partsInsensitive to dirt and contaminationUtilizes the factory style mounts, connectors and fittingsProvides exceptional reliability
