2015 Mercedes-Benz GLK-Class Air Filter in Sudbury, MA

The engine air filter sits in the engine bay inside a sealed airbox (typically passenger‑side), and the cabin filter is located behind the glove box.

This layout is common on the 2015 Mercedes-Benz GLK-Class with the 2.1L twin‑turbo diesel. The airbox houses the panel filter that feeds clean air to the intake, while the cabin microfilter is mounted in the HVAC housing. If access is tight or clips are stubborn, our Sudbury team can help.

Keeping both fresh supports smooth torque delivery (up to 369 lb‑ft) and comfortable ventilation. Genuine Mercedes‑Benz elements fit correctly and seal as designed.
