It sits in a rectangular airbox in the engine bay, typically near the front corner of the compartment.

On the 2017 Mercedes-Benz CLA-Class, the engine air filter lives inside the intake airbox under the hood; clips or screws secure the lid. For reference, the cabin air filter is separate and usually accessed behind the glove box inside the cabin.

• Open hood and locate the intake airbox
• Release clips/screws to inspect the panel filter
• Cabin filter: behind glove box access panel

The engine filter cleans intake air for the 2.0L turbo engine; the cabin filter cleans air entering the HVAC for passengers.

Both filters serve different systems on the 2017 Mercedes-Benz CLA-Class. A restricted engine filter can reduce power and mpg; a dirty cabin filter affects airflow and comfort. Each has its own service interval and replacement access points.

• Engine: protects combustion and MAF sensor
• Cabin: protects occupants and HVAC components
• Replaced independently based on condition

Common signs include reduced power, lower fuel economy, rough idle (engine), and weak HVAC airflow or musty odor (cabin).

If your CLA feels sluggish or your mpg drops, the engine filter may be restricting intake air. Inside the cabin, a stale smell or poor defrost performance often points to a loaded cabin filter. An inspection can confirm condition and replacement timing.

• Engine: hesitation and poorer mpg
• Cabin: weak airflow, fogging, odors
• Visual check: dark, debris-filled media

Yes—engine filters are often DIY-friendly, while cabin filters may require trim removal that’s easier for a technician.

Many owners can swap the engine filter with basic tools, but the cabin filter’s access behind the glove box can be tight. Dealer service adds an intake housing and MAF visual check and ensures the correct OEM-spec media is installed and sealed properly.

• DIY: engine filter clips and cover
• Dealer: intake/MAF inspection and fitment
• Schedule service if you prefer pro install
