Detailed Description

Wix 42073 is an engine air filter made for OEM-style service intervals and consistent airflow management. The cellulose media is treated to improve durability against moisture ingestion, while the panel-style construction supports filtration performance in stop-and-go traffic, dirt roads, construction sites, short trips, and interstate driving. This part cross-references Ford (e.g., D2AF9601AA, E0TZ9601A) for the same application.

Compatible With Ford F-150, Ford Bronco, Ford E-150 Econoline, Ford E-250 Econoline, Ford E-350 Econoline, Ford Thunderbird, Lincoln Town Car, Mercury Cougar, and Mercury Grand Marquis applications across the listed model years. The Wix 42073 is also a direct service choice for many Ford LTD, Lincoln Continental, and Mercury Marquis fitments.

What It Helps Address

• Restricted airflow from a dirty or loaded engine air filter
• Dust and debris entering the intake system during road use
• Moisture-related media breakdown in humid or wet conditions
• Reduced filtration performance during frequent stop-and-go driving
• Premature service replacement when an OEM-style interval is needed

Installation Notes and Tips

Verify the air box dimensions and match the filter to the vehicle’s original application before installation. Replace the filter at regular service intervals, especially if the vehicle is driven on dirt roads, in heavy traffic, or in other severe-duty conditions. Confirm fitment for the exact year and model, including late-production 1977 Ford LTD and Thunderbird applications where noted.

Quality Assurance

Wix manufactures this filter to meet OEM air filter change interval expectations and backs its filtration design with ISO 5011 laboratory testing data. The construction uses durable media and sealing materials selected for long service life in normal and severe driving environments.
