Protec 472 Engine Air Filter - Main

Engine Air Filter for Toyota and Lexus Applications

Detailed Description

Protec 472 is designed as an OE-style engine air filter for vehicles that call for Toyota and Lexus original equipment part numbers such as 178010P051, 17801YZZ11, and 1780131131. The panel-style construction and enhanced cellulose media are sized to match the original media area, helping support consistent airflow and filtration during normal service use. This makes it a practical replacement for drivers servicing a Lexus RX350, Toyota Highlander, or Toyota Sienna, as well as related Camry, Avalon, ES350, NX300, and NX200t applications. The Protec 472 part number is also cross-referenced by Wix 49430 for the same application.
