Detailed Description

WIX 46878 is an HD engine air filter designed around the dimensions and airflow demands of heavy-duty equipment and commercial vehicles. The filter uses cellulose media with a metal-ended structure to help maintain shape and filtration performance during OEM air filter change intervals. Its 1100 CFM rating supports engines that require substantial intake volume, while the closed top and tapered body dimensions help ensure proper seating in the air cleaner housing. This part cross-references Donaldson P150692 and Fleetguard AF1850 for the same application.

For buyers searching for a WIX 46878 air filter, WIX HD air filter 46878, or a heavy-duty engine air filter for commercial diesel intake service, this part is built to match the physical and performance requirements of the application. It is also a relevant replacement search for equipment using WIX 46878, including select Caterpillar and General Motors cross-reference applications.

What It Helps Address

• Restricted airflow caused by a loaded engine air filter
• Dust and debris entering the intake system
• Premature wear from inadequate air filtration
• Loss of intake efficiency in heavy-duty service
• Filter housing fit issues when the correct dimensions are required

Installation Notes and Tips

Verify the housing dimensions before installation, including height, bottom outer diameter, and top diameter. Confirm the filter seats evenly in the air cleaner assembly and that the closed-top design matches the original configuration. For fitment-based searches, this part is commonly referenced for heavy-duty applications rather than passenger-car use, including WIX 46878 and related OEM replacement searches.

Quality Assurance

WIX states that this HD air filter line is laboratory tested to ISO 5011 standards and built with durable end-cap and body materials for long service life. The manufacturer recommends replacement at OEM air filter change intervals.
