Detailed Description

Wix 42029 is an engine air filter engineered for heavy-duty filtration needs. The premium media, pleat stabilization features, and reinforced construction are intended to maintain filtration performance while supporting long service intervals. Laboratory testing per ISO 5011 reports minimum efficiency of 99.9% contaminant removal, based on Wix reference filters.

This part cross-references Vortox VF120W and Donaldson P608653 for the same application. It is a direct fit for select Freightliner Classic, Freightliner FLD132, and Freightliner Classic XL applications, making it a practical replacement for service work on these trucks.

What It Helps Address

• Restricted airflow caused by a loaded or dirty engine air filter.
• Dust and debris entering the intake system.
• Reduced filtration performance during scheduled maintenance.
• Premature wear from inadequate intake air cleaning.
• Service intervals that require a replacement filter meeting OEM timing.

Installation Notes and Tips

Verify the existing filter dimensions and seal style before installation. Confirm the housing accepts a radial seal air filter with the listed dimensions, and inspect the air cleaner housing for dirt or damage before fitting the new filter. Use the vehicle's service schedule and replace the filter at the recommended interval.
