The engine air filter should be replaced every 10,000 miles. There are two air filters in your Mercedes-Benz. They are both on the engine cover, which you can see in the pictures below. Replacement is easy if you have a Torx tool set like the one below. The whole job only takes about 30 minutes max. These instructions apply to most Mercedes-Benz cars from 2000 to 2011. You can see the applications list at the end of the article. You will find step-by-step instructions on changing the engine air filters and a video here.

- Locate the engine cover. Grab it on the sides and lift it. The whole engine cover is held in place with four clips. The cover comes off with pressure—no need to remove any screws other than the air ducts.
- Flip the engine cover upside down and locate the air filters.
