This OEM‑spec crankcase ventilation suction line A2740905600 is a direct replacement part for Mercedes‑Benz vehicles equipped with M274 1.8L & 2.0L turbo engines, covering W205 C‑Class, X253 GLC, W213 E‑Class, C218 CLS and R172 SLC models.
This hose connects the crankcase ventilation system to the intake pipeline, transporting blow‑by gas smoothly. Long‑term high‑temperature exposure will cause rubber aging, cracking, vacuum leakage, rough idle and increased oil consumption. Honya adopts compound‑modified EPDM rubber material with excellent heat resistance and oil resistance to adapt to harsh engine bay working conditions.
Precision 1:1 molding matches original interfaces perfectly for plug‑and‑play installation without extra modification. It restores normal crankcase ventilation function, eliminates leakage faults and keeps M274 engine running stably for a long time, which is a reliable aftermarket spare for repair shops and wholesale clients.
