Mercedes-Benz CLA Air Filter Replacement Parts

Every CLA has an air filter regardless of engine or fuel type — petrol, diesel, and even the hybrid variants all require one to clean intake air before it enters the engine. The filter design and housing will differ between engine families, so the part you need is determined primarily by your engine code rather than anything else. Check your V5 or run a VIN check to confirm your exact engine code before sourcing a used filter.

The C117 and C118 are different platforms with different engine bay layouts, so an air filter housing and element from a C117 is very unlikely to directly interchange with a C118 even if the engine displacement sounds similar on paper. Although Mercedes carried some engine families across generations, the airbox packaging typically changed with the new body, so you should not assume cross-generation compatibility. Name both your generation and engine code clearly when asking a breaker, and confirm fitment against your registration before buying.

The C117 received a facelift in 2016 that was largely cosmetic, but some under-bonnet ancillary components can change mid-production run even within a generation. If both cars share the same engine code, the air filter element itself is very likely identical, but confirm any housing or mounting details with the breaker against your specific registration to be certain.

Trim level makes no difference to air filter fitment on the CLA — AMG Line, Sport, and Urban are cosmetic and equipment packages, not mechanical ones. What matters is your engine code, which is shared across trims fitted with the same engine. Give the breaker your engine code rather than your trim name and you will get the right part far more reliably.

The 220d and 200d are both diesel engines but they are different states of tune within the OM651 or OM608 engine family depending on year, and they may or may not share the same airbox and filter. Rather than relying on the badge, supply your exact engine code to the breaker — it is printed on your V5 or available from a VIN check — so they can match the part precisely rather than guessing from the displacement figure.

Air filter elements are inexpensive new, so for the paper or foam element alone a new pattern or OEM part is often the more practical choice. However, if you need the complete airbox housing, pipe, or mass airflow sensor as an assembly — perhaps because yours is cracked or missing — a used unit from a breaker can be good value, and that is where confirming the engine code becomes especially important. Tell the breaker exactly what you need (element only, or full housing assembly) and confirm compatibility against your registration.
