2020 Mercedes-Benz GLB-Class Air Filter in Sudbury, MA

The 2020 Mercedes-Benz GLB-Class engine air filter sits inside a sealed airbox in the engine bay, while the cabin filter is behind the glove box.

This SUV’s 2.0L turbocharged inline-4 draws intake air through a panel-style filter housed in the airbox for easy access during service. The cabin microfilter is typically accessed by removing the glove box panel. If you prefer a technician to handle trim clips and seals, schedule an appointment in Sudbury.
