Wix 42055 Engine Air Filter

The Wix 42055 engine air filter is built for Ford Bronco, F-100, F-150, F-250, F-350, and Econoline applications that need dependable intake filtration. It uses enhanced cellulose media and a durable seal design to help maintain airflow while capturing airborne contaminants from everyday and severe-duty driving.

Key Features

• Premium panel-style engine air filter for light-duty vehicles
• Enhanced cellulose media with phenolic resin treatment for added moisture resistance
• 30% more media than comparable OES filters, based on manufacturer design data
• Laboratory-tested to at least 99.5% efficiency per ISO 5011, based on Wix 42389
• High-tear strength polyurethane seal for hot and cold temperature exposure when applicable
• 120 CFM rating for intake airflow support
• Direct replacement for Wix 42055 and select cross-reference applications

Detailed Description

Wix 42055 is an engine air filter designed to support clean intake air in older Ford truck and van platforms, including 1965-1986 Ford Bronco, F-Series, and Econoline models, plus select Mercury applications. The filter measures 3.220 inches high with an 8.400-inch top and bottom outer diameter and a 6.580-inch inner diameter at the bottom. Its cellulose media is treated to improve durability against moisture ingestion, while the seal construction is intended to hold up under temperature swings common in daily driving and work use. This part cross-references Monroe Shocks & Struts (e.g., 39251) for the same application.

What It Helps Address

• Restricted airflow caused by a dirty or loaded engine air filter
• Dust ingestion during stop-and-go traffic, dirt roads, and construction zones
• Reduced filtration performance during short-trip driving
• Air intake contamination in Ford Bronco and F-Series service intervals
• Maintenance replacement for Econoline and Club Wagon air filter service

Installation Notes and Tips

Verify the housing dimensions and match the filter to the existing air cleaner before installation. Replace the filter at OEM-recommended service intervals, or sooner if the vehicle is driven in dusty or severe conditions. Confirm fitment for the exact year, engine, and emissions configuration on Ford Bronco, F-100, F-150, F-250, F-350, and Econoline models before ordering.

Quality Assurance

Wix designs this filter for normal and severe driving conditions and validates filtration performance through ISO 5011 laboratory testing. The premium media construction and moisture-resistant treatment support consistent service life in demanding intake environments.
