On the 2014 Mercedes-Benz GLK-Class with the 2.1L inline‑4 twin‑turbo diesel (engine code 4ITTD2.1), the panel‑style element is secured in a plastic airbox with clips or screws. Access typically involves unclipping the housing and lifting the cover to remove the filter. For comparison, the cabin filter is typically behind the glove box area on the passenger side.

In your 2014 Mercedes-Benz GLK-Class, the engine air filter supports performance and efficiency by keeping debris out of the turbocharged intake and MAF sensor. The cabin filter targets dust, pollen, and particulates for cleaner interior air and stable HVAC airflow. Replacing both at proper intervals preserves drivability and comfort in Greater Boston traffic.
