Mercedes-Benz C-Class — 空气滤芯
Why Air Filter Matters on the C-Class
The engine air filter stops dust, sand and debris from entering the M271/M274/M264 engine. In Malaysia's dusty city conditions and construction-heavy roads, a clogged filter raises fuel consumption by 5–10% and can cause rough idle or sluggish throttle response.
Replacement Interval
- W204 M271: every 30,000 km or 2 years
- W205 M274/M264: every 30,000 km — ASSYST may prompt earlier in dusty conditions
- W206 M264: every 30,000 km
OEM vs Aftermarket
Use OEM Mann or Mahle filters — they are the actual Mercedes supplier. Cheap generic filters collapse under high airflow and allow fine particles through. OEM filter cost ; workshop labour .
