Engine Air Filter vs Cabin Air Filter

The 2020 Mercedes-Benz GLS-Class benefits from both a properly functioning engine air filter and a clean cabin air filter; each plays a distinct role in reliability and comfort. The engine air filter ensures the turbocharged 3.0L inline-6 receives clean air so horsepower and torque—362 hp at 5,500 rpm and 369 lb-ft at 1,600 rpm—remain consistent. A clogged engine filter forces the engine to work harder, reducing fuel economy and increasing wear. The cabin air filter protects occupants by filtering out pollen, dust, and road pollutants, keeping HVAC systems efficient and passenger comfort high. At Mercedes-Benz of Draper in Draper, UT, our factory-trained technicians inspect both filters during routine maintenance and recommend OEM replacements when necessary. We emphasize transparent pricing, genuine parts, and documentation of all work so you understand immediate and long-term savings. For convenience and peace of mind, schedule service online and ask about current service specials and service financing options to get the care your GLS-Class deserves.
