Engine Air Filter vs Cabin Air Filter

The 2025 Mercedes-Benz GLS-Class requires two distinct filtration systems to protect both the engine and the cabin environment. The engine air filter safeguards the turbocharged 3.0L inline engine from dust and debris that can harm the turbocharger and reduce horsepower and torque; maintaining a clean engine filter helps preserve the GLS-Class’s rated performance and fuel efficiency. The cabin air filter keeps pollen, dust, road particles, and odors out of the passenger compartment, ensuring a healthy and comfortable interior for drivers and passengers. At Mercedes-Benz of Draper in Draper, UT, our factory-trained technicians inspect both filters as part of standard maintenance. Using OEM parts and exacting installation practices, we extend component life and reduce the chance of costly repairs later. Regular replacement of both filters offers immediate benefits—better airflow, improved fuel economy, and cleaner cabin air—and long-term savings through protected engine health.

At Mercedes-Benz of Draper, we recommend inspecting the cabin filter at routine service intervals and replacing it based on condition—more often for drivers exposed to heavy traffic or dusty roads.
