Walker 245-3117 Mass Air Flow Sensor
Walker Complete Assembly Mass Air Flow Sensor
Walker 245-3117 is a complete assembly mass air flow sensor built for direct replacement on select Nissan and INFINITI applications. It is a 100% new, never remanufactured sensor that is programmed and tested for fit, form, and function before release.
This Walker Complete Assembly line includes sensor and housing assemblies for applications where the housing should be replaced along with the sensor. The design uses OEM-quality components, a custom engineered circuit board, and tuned flow characteristics to match the vehicle’s airflow range.
Key Features
