Hitachi MAF0081 Mass Air Flow Sensor OEM

The Hitachi MAF0081 Mass Air Flow Sensor is a new original equipment part designed to measure the volume and density of air entering the engine. Accurate MAF readings are critical for the engine control unit to calculate proper fuel injection and ignition timing, and this sensor is precision-manufactured to meet OE performance and durability standards. Each unit undergoes rigorous airflow testing and emissions calibration before leaving the factory, ensuring it delivers measurements that match the original sensor's specifications.

A notable design feature is the built-in contaminant bypass port, which channels airborne particles away from the delicate sensing elements. This helps the sensor resist fouling from dust and debris over time, contributing to a longer operational lifespan and more reliable readings. The flange mount design allows straightforward replacement of a worn or failed sensor, and at just 4 ounces with dimensions of 6.67 x 5.05 x 4.62 inches, it integrates into the intake tract without adding notable weight or bulk.
