KENWORTH T680 CABIN AIR FILTER LOCATION:

• Go to the passenger side of the truck.
• Open the passenger door and locate the plastic access panel on the firewall behind the glove box or below the dash area.
• The panel is typically held by plastic clips or screws.
• Remove the panel to expose the cabin air filter housing.
• Slide out the old filter and replace it with a new one. Ensure the airflow direction arrow points correctly.

📌 Note: Not all Kenworth T680 trucks come with a cabin air filter from the factory. If your truck does not have one, you may still be able to install it if the housing is present. Also, some newer T680 models use a thin, sponge-like cabin filter. If this matches your truck, use the AF55836 Cabin Filter found here.
