1. Locate the air filter cover on the top of your BMW 330 engine. It will be a black cover, secured by seven torx screws. You should see it near the center of the engine on top with a black flex hose running from the cover to the engine.
2. Remove torx screws with torx screwdriver from top cover of air filter. Lift the cover up. It will not come all the way out, just enough to give clearance to remove the air filter.
3. Unclip the flex hose from the air cleaner to provide room for removal. You will see a pin inserted into the air filter. Pull the pin back and remove the filter from the air cleaner.
4. Replace the air filter with a new filter by pulling the pin back and reinserting the new filter. Replace the flex hose on the front of the air cleaner.
5. Place the cover back on the air cleaner and secure it with torx screws.

1. Park the Mercedes Benz CLK 320 in a safe work area.
2. Open the passengers side door and squat down beside the drivers side door. Shine a flashlight underneath the glove compartment and locate the access panel directly under the glove box. Remove the screws from the access panel with a screwdriver. Place the screws in a safe area, such as on the drivers seat.
3. Pull down the access panel and place it in the drivers seat. Shine the flashlight through the access panel opening and locate the black square box directly behind the glove box. The black square box houses the cabin air filter and has a sliding bracket on top.
4. Pull the front part of the sliding bracket toward the passengers seat and push the adjoining sliding bracket toward the front of the vehicle. This will expose the cabin air filter. Grab the lower back part of the cabin air filter and rotate it downward until it comes out of the box. Make a mental note of the direction of the air flow arrow on the old cabin air filter.
5. Install the new cabin air filter with the air flow arrow pointing in the same direction in which the arrow on the old filter pointed. Slide both sliding brackets back toward each other to close the top of the square box over the top of the new cabin air filter.
6. Reassemble the bottom access panel with the removed screws, and tighten the screws with the screwdriver. Discard the old cabin air filter.
