Filter Construction and Fitment

This WIX 49013 air filter uses cellulose media and a closed top with a 2.834-inch inner diameter at the bottom, 5.354-inch outer diameter at the bottom, and 8.677-inch overall height. The design is intended to maintain airflow while capturing airborne contaminants before they reach the engine intake system. This part cross-references FRAM CA9800 and Purolator A38213 for the same application.

Common Problems This Filter Can Address

• Restricted airflow caused by a dirty or clogged engine air filter
• Dust and road debris entering the intake system
• Reduced filtration performance during stop-and-go driving
• Moisture-related filter breakdown in demanding weather conditions
• Premature wear from contaminated intake air

Installation Notes and Quality Assurance

Install the filter in the factory airbox and confirm the housing is clean before sealing it in place. Check the filter orientation against the airbox design and inspect the sealing surface so the element seats evenly. For service intervals, follow the vehicle manufacturer’s air filter replacement schedule unless inspection shows earlier restriction.

WIX designs this filter for OEM-style replacement intervals and validates performance through ISO 5011 laboratory testing. The construction focuses on durability, moisture resistance, and consistent filtration for Volkswagen Jetta, Audi A3, and related applications.
