Detailed Description

The Wix WA11189 is an engine air filter designed to replace the factory panel filter in select Toyota and Lexus vehicles. It uses cellulose media treated with phenolic resin to improve durability in damp conditions, while the panel construction supports consistent airflow and filtration performance during stop-and-go driving, short trips, dirt-road use, and highway travel. The WA11189 is recommended for OEM air filter change intervals and is cross-referenced to Beck/Arnley 042-1949 and Delphi AF10115 for the same application.
