Among Wix engine air filters, the 42731 is cataloged in the HD duty type. It traps contaminants in the incoming air before that air reaches the engine. Over time the media loads with dirt, which can restrict intake airflow. Signs this part may need replacing include visible dirt buildup on the media or a filter that is past its scheduled change interval. A fresh filter helps restore proper airflow for normal engine performance. The listed applications use one filter.
