Technical Details and Specifications

The Wix 42971 engine air filter is constructed with cellulose media, which provides reliable filtration by trapping dust and debris while maintaining airflow necessary for engine performance. Its radial seal design offers a tight, secure fit to prevent unfiltered air bypass.
