Keep clean, filtered air moving into the intake of your heavy-duty diesel with the WIX Radial Seal Air Filter 46843, a direct-fit replacement for a long list of Class 8 trucks — including the 1996-2007 Freightliner Century Class [L6-12.7L], Freightliner Classic, Freightliner Columbia, Kenworth C500, Kenworth T600A, and Kenworth T800 [6-12.0L]. It covers 229 applications across Freightliner and Kenworth models, so see the Buyer's Guide tab for the full year-make-model-engine list.
WIX HD air filters are laboratory tested to ISO 5011 and are recommended for OEM air filter change intervals. A clogged or dirty air filter can restrict airflow — if a loaded filter is the cause, replacing it helps restore proper airflow for normal engine operation. Applications call for one or two filters depending on the truck; this listing is for one filter. Country of origin: United States. Manufacturer part number 46843.
