Detailed Product Description

The Bosch 5184WS is an OE-style engine air filter designed to service the intake system on vehicles such as the Toyota Camry, Toyota Avalon, Toyota RAV4, Lexus ES300h, Lexus LS460, Lexus LS600h, and Lexus HS250h. Its pleated panel construction helps maximize media area, while the cellulose filter media is engineered to capture airborne contaminants before they reach the engine.

This Bosch Workshop Air Filter line is built around consistent airflow, sealing integrity, and filtration efficiency. The polyurethane frame seal helps the filter maintain contact in the airbox, reducing the chance of unfiltered air bypassing the media. If you are replacing a worn engine air filter on a Toyota Camry or Lexus ES300h, Bosch 5184WS provides a direct service part reference for routine maintenance.

This part cross-references Toyota/Lexus OE numbers 178010V020 and 1780138011 for the same application.

What This Air Filter Helps Address

• Restricted airflow caused by a dirty or loaded engine air filter
• Dust and debris entering the intake system
• Reduced filtration performance from a worn filter element
• Seal leakage around the air filter perimeter
• Routine maintenance needs on Toyota and Lexus intake systems

Installation Notes and Tips

Verify the air filter shape and part number before installation. Confirm fitment against the vehicle’s year, make, and model, especially on Toyota Avalon applications with different production notes. Inspect the airbox for dirt or debris before installing the new filter, and make sure the seal seats evenly in the housing.
