Engine Air Filter vs Cabin Air Filter

Understanding the difference matters for maintenance of your 2018 Mercedes-Benz GLS-Class. The engine air filter protects the engine and turbocharger, improving fuel economy, throttle response, and emissions control; the cabin air filter protects occupants by keeping incoming air clean. Both filters are inexpensive insurance against greater repair bills: a clogged engine filter increases engine wear and reduces efficiency, while a neglected cabin filter can stress the HVAC blower and reduce interior air quality. At Park Place Motorcars Fort Worth we inspect both filters as part of routine service and recommend replacements based on condition, not arbitrary schedules. We install OEM parts to maintain performance and warranty integrity, and our factory-trained technicians provide a clear explanation of any recommended work.
