Second Hand Mercedes-Benz CLS Air Filter

Yes, every CLS variant has an air filter regardless of whether it is petrol or diesel, because all internal combustion engines need to filter the air entering them. The CLS has never been offered as a hybrid or electric model in the UK, so there are no exceptions within the range. When searching for a used air filter, the key detail to nail down is your exact engine code rather than just the fuel type.

Almost certainly not — the C219 and C218 are completely different generations with different engine families, so the airbox and filter dimensions changed between them. Even where engine displacement looks similar on paper, the engine codes differ across that 2011 generation boundary, which is what drives filter fitment. Always confirm compatibility with the breaker against your exact registration or engine code before buying.

The C218 received a facelift in 2014 but this was primarily styling and minor equipment updates rather than a fundamental engine change, so in many cases the air filter will be the same before and after the facelift. However, some engine variants were revised or replaced around that period, so the engine code on your V5 or a VIN check is the safest way to be certain. Confirm the specific part number with the breaker against your registration to be sure.

Trim level alone does not affect air filter fitment — what matters is the engine code fitted to your car, not whether it is badged Sport, AMG Line, or a full AMG variant. A 350d AMG Line and a 350d Sport share the same engine and will take the same filter. Where a true AMG model (such as the CLS 63 AMG) has a different engine code from the standard range, it will need its own specific filter, but that is down to the engine, not the trim name.

Yes, diesel and petrol engines use different airbox and filter configurations, so a filter from a petrol CLS will not be correct for a diesel CLS even if the cars are from the same year and generation. The engine code (for example a 350 BlueTEC diesel versus a 350 petrol) confirms exactly which filter housing and element you need. Always supply your engine code to the breaker so they can pull the right part.

Possibly — Mercedes-Benz shared engine families across several models, so the same engine code can appear in the CLS, E-Class (W212) and S-Class, and where the full engine variant matches exactly, the filter element may well be identical. However, airbox mounting and housing designs can differ between body styles even with the same engine, so you cannot assume the whole assembly is interchangeable. Give the breaker both your CLS registration and the source vehicle's registration and ask them to cross-reference the part numbers before committing.
