Where is the engine air filter located on a 2020 Mercedes-Benz CLS-Class?

The engine air filter sits in a sealed airbox within the engine bay, while the cabin microfilter is typically behind the glovebox.

The 2020 Mercedes-Benz CLS-Class uses a dedicated intake airbox to feed its 3.0L inline-6 turbocharged engine, helping protect the MAF and turbo from debris. The cabin filter is positioned upstream of the HVAC blower to clean air entering the passenger compartment. If you prefer professional service near Lynnfield or Greater Boston, schedule an appointment and we’ll verify both filter locations on your CLS.

  • Engine air filter: sealed airbox in the engine compartment
  • Cabin air filter: commonly accessed behind the glovebox

Whats the difference between an engine air filter and a cabin air filter on a 2020 Mercedes-Benz CLS-Class?

The CLS uses two filters: one engine intake filter for combustion and one cabin microfilter for passenger air through the HVAC system.

The engine filter protects the 3.0L inline-6 turbo by trapping dust before it reaches the intake and sensors, supporting performance and efficiency. The cabin filter cleans outside air before it enters the interior, helping reduce dust and odors. Replacing both on time preserves acceleration feel and keeps the cabin comfortable for commutes around Lynnfield and the North Shore.

  • Engine filter: safeguards intake, turbo, and MAF from debris
  • Cabin filter: improves in-cabin air quality and HVAC performance
  • Check service specials before you schedule
What are the signs of a clogged air filter on a 2020 Mercedes-Benz CLS-Class?

Common signs include 1) reduced power or MPG for the engine filter and 2) weak airflow or musty odors for the cabin filter.

On the 2020 Mercedes-Benz CLS-Class, a restricted engine filter can dull throttle response and make the 362-hp inline-6 feel less lively. A saturated cabin filter can reduce defogging performance and blower volume, especially during high-pollen seasons around Greater Boston. If you notice these symptoms, we can inspect both filters during the same visit.

  • Engine: sluggish acceleration, rougher idle, lower fuel economy
  • Cabin: weak vents, increased window fogging, stale or musty smell
  • Book a diagnostic check: schedule now
Can I replace the air filter on my 2020 Mercedes-Benz CLS-Class myself, or should the dealer do it?

Yesthe engine filter is generally DIY-friendly, while the cabin filter often needs trim removal and is simpler at a dealership.

Many owners can swap the engine filter using basic tools, but the cabin filter location and panels can be finicky on the 2020 Mercedes-Benz CLS-Class. Dealer service adds an intake seal check and a visual MAF inspection to prevent leaks that can affect drivability. If you want a quick, verified result in Lynnfield, book a visit online.
