The 2020 Mercedes-Benz CLS-Class CLS 450 uses two distinct filters that serve different roles: the engine air filter preserves power and efficiency for the 3.0L inline turbocharged engine, while the cabin air filter protects interior air quality for passengers. Maintaining both is critical. A clean engine air filter ensures the turbocharger breathes freely, supporting the 362 hp output and preserving fuel economy (24 city / 31 highway). A clogged engine filter increases strain on moving parts and can accelerate wear, leading to higher repair bills down the road. The cabin filter, meanwhile, affects HVAC performance, allergen removal, and odor control—especially important in urban or dusty environments around Arlington, TX. At Park Place Motorcars Arlington we inspect both filters during routine service, recommend OEM replacements when needed, and explain long-term savings to help you make an informed decision.
