Detailed Product Overview

Wix 46799 is an engine air filter designed to service the intake system on many Mercedes-Benz models from 1999 through 2016. The filter measures 13.976 inches long, 5.295 inches wide, and 1.969 inches high, with a closed inner diameter top and an air filter panel style construction. Its cellulose media is treated to improve durability against moisture ingestion, while the polyurethane seal is used where applicable to help maintain a stable fit through temperature changes. This part cross-references FRAM CA8768 and Mann-Filter C 3698 for the same application.

What This Air Filter Helps Address

• Restricted airflow caused by a dirty or loaded engine air filter
• Excess intake contamination from dust, dirt roads, and stop-and-go traffic
• Reduced filtration performance during short-trip and severe-duty driving
• Moisture-related media breakdown in demanding weather conditions
• Service replacement needs for Mercedes-Benz air filter maintenance intervals

Installation Notes and Tips

Verify the filter dimensions and OE reference numbers before installation, especially on Mercedes-Benz E-Class, GL-Class, ML-Class, and SLK-Class applications. Replace the air filter at the manufacturer-recommended service interval, and inspect the airbox for debris before installing the new Wix 46799. Confirm the fitment notes for vehicles such as the 2012 Mercedes-Benz SLK55 AMG, 2011 Mercedes-Benz GLK300, and 2008-2009 Mercedes-Benz S450.
