Detailed Description

The Hengst E905LI cabin air filter is specified for interior HVAC filtration on select Audi and Volkswagen vehicles. Its particulate media is intended for applications that call for a pollen filter, helping trap airborne dust and other fine particles before they enter the cabin through the HVAC system. This part number is used across multiple fitments, including 1996-2001 Audi A4, 1996-2001 Audi A4 Quattro, 2000-2001 Audi S4, and 1998-2000 Volkswagen Passat. It also applies to 1994-1998 Audi Cabriolet, 1994-1995 Audi 90, and 1994-1995 Audi 90 Quattro. If you are searching for an Audi A4 cabin air filter or a Volkswagen Passat pollen filter, E905LI is the relevant Hengst reference.

This part cross-references Gates 24774 for the same application.

What It Helps Address

• Dust entering the HVAC intake
• Pollen and other fine airborne particles in the cabin
• Reduced interior air cleanliness from a loaded filter
• HVAC airflow restriction caused by a clogged cabin filter
• Interior air filtration service intervals on older Audi and Volkswagen models

Installation Notes and Tips

Verify the vehicle year, make, model, and notes before ordering, especially for the 2001 Volkswagen Passat application with the listed production breakpoint. Replace the cabin air filter according to the vehicle service schedule or sooner if airflow drops or the filter is visibly loaded. Confirm the filter orientation and housing style during installation so the particulate media is seated correctly in the HVAC case.

Quality Assurance

Hengst is an established filtration brand, and the E905LI is built as a particulate cabin air filter for the listed Audi and Volkswagen applications. Use the fitment notes to confirm the correct interior air filter for your vehicle before installation.
