Detailed Description

Built for HD duty cycles, the WIX 46919 engine air filter is engineered to maintain intake cleanliness while supporting consistent airflow. Its radial seal design, 21.400-inch height, 11.380-inch top and bottom outer diameter, and 6.800-inch inner diameter bottom help it match the dimensions required for specific heavy-duty intake housings. This part is a direct-fit style replacement for applications that call for a WIX 46919 air filter, including select commercial and vocational vehicle platforms such as Freightliner and International models where this size and seal style are specified.

For buyers searching for a WIX 46919 air filter, heavy-duty radial seal engine air filter, or replacement air filter for Freightliner and International applications, this part provides a serviceable option built around durable construction and filtration-focused media. It is also cross-referenced to common aftermarket and OE-style numbers such as Baldwin RS4564 and Donaldson P542753.

What It Helps Address

• Dust and airborne debris entering the engine intake
• Restricted airflow caused by a worn or loaded air filter
• Premature intake contamination in HD service
• Maintenance intervals that require an OEM-style air filter replacement

Installation Notes and Tips

Verify the housing dimensions, seal style, and flow direction before installation. The filter is designed for inside-out airflow, so the orientation must match the intake system. Confirm the application by part number and housing measurements when servicing Freightliner or International vehicles, since heavy-duty air filter housings can vary by engine and chassis configuration.

Quality Assurance

WIX HD air filters are built with premium filtration media, pleat stabilization features where applicable, and durable end-cap and body materials for long service life. Laboratory testing referenced by WIX indicates minimum 99.9% contaminant removal under ISO 5011 test conditions.
