Engine Air Filter vs Cabin Air Filter

The engine air filter and the cabin air filter serve distinct but equally important roles on a 2020 Mercedes-Benz GLS-Class. The engine air filter protects the inline 3.0 turbocharged powerplant from dust and particulates, helping maintain the vehicle’s rated 362 horsepower and efficient fuel consumption. The cabin air filter, by contrast, cleans the air that you and your passengers breathe, removing pollen, dust, and odors so every drive in Fort Worth is more comfortable and healthier. Maintaining both filters preserves performance and comfort: a clogged engine filter forces the engine to work harder, while a blocked cabin filter reduces HVAC effectiveness. At Park Place Motorcars Fort Worth we evaluate both filters during routine service, using OEM replacements and factory-calibrated diagnostics to ensure proper fit and filtration. Keeping both filters in top condition reduces long-term wear on the turbocharger, sensors, and HVAC system, translating to fewer repairs and better resale value.
