Installation Notes and Tips

Verify the filter dimensions, style, and end configuration against the original air filter before installation. Confirm that the 19-inch length, 7.25-inch width, and 7.125-inch height match the housing requirements, and compare the closed-top design to the existing part. For fitment-based searches, use the vehicle catalog to confirm the exact application before ordering a WIX WA11077 replacement air filter for Ford F-250 or Ford F-350 service.

Because fitment data is not provided in the supplied catalog record, no vehicle-specific installation position is listed here. Replace the filter according to the vehicle or equipment maintenance schedule and inspect the housing for dirt buildup during service.
