Installation Notes and Tips

Verify the housing dimensions and part number before installation to confirm the correct Mercedes-Benz E320 fitment. Inspect the air box for dirt, leaves, or debris before installing the new filter, and make sure the filter seats evenly in the housing so unfiltered air does not bypass the media. Replace the filter at the manufacturer-recommended service interval or sooner if driving conditions are severe.
