Installation Notes and Tips

Replace the filter at the vehicle’s recommended service interval or sooner if driving conditions are severe. Before installation, inspect the airbox for dirt, leaves, or debris and confirm the filter seats evenly in the housing to maintain a proper seal. Verify application by year and model before ordering WIX 49120.
