Detailed Description

This Bosch Workshop Air Filter, part number 5963WS, is engineered with a high number of pleats to increase filtering surface area while maintaining airflow. The cured cellulose media is intended to trap outside particles before they reach the engine, and the polyurethane seal helps preserve the filter surface and sealing integrity over time. It is a direct fit for select Lexus TX350, Toyota Avalon, and Toyota Camry applications, including Fits 2018-2019 Toyota Camry, N/A and Fits 2019 Toyota Avalon, N/A. This part cross-references Monroe Shocks & Struts (e.g., 1780125020) for the same application.
