This replacement air filter is an application for the 2017-2018 Chevrolet Cheyenne, 2001-2005 Chevrolet Silverado 2500 HD, 2001-2005 Chevrolet Silverado 3500, 2001-2005 GMC Sierra 2500 HD, and 2001-2005 GMC Sierra 3500. It sits in the air intake path and cleans the air drawn into the engine, so the intake receives filtered air.
- Filtration: Traps dust, dirt, and airborne debris from incoming air before it reaches the intake and combustion chambers.
- Airflow: A clean element helps restore proper airflow for normal engine performance.
- Service item: A routine maintenance replacement that installs in the factory air box.
Signs this filter may need replacing include a visibly dirty or clogged element and reduced intake airflow. If a restricted air filter is the cause of the issue, replacing it with the 46678 renews the intake's filtration. Follow the vehicle's recommended service interval and inspect the element periodically.
