To meet the aftermarket demand of Mercedes-Benz M274 engine series, Huaxiang Factory manufactures the crankcase ventilation hose marked OE 2740182400, which is delivered to worldwide auto spare parts markets via Honya’s foreign trade channels. Its vehicle coverage includes Mercedes C-Class, E-Class, GLC, CLS, GLK and SLC classes.
This hose undertakes the core task of circulating crankcase blow-by gas. Original factory hoses tend to harden and develop micro leaks after long-term exposure to high-temperature oil vapor, bringing troubles such as unstable cold start idle speed, oil buildup inside intake manifold, excessive emissions and frequent engine trouble codes. Huaxiang adopts reinforced EPDM raw material to improve anti-aging and deformation resistance. All interface tolerances are calibrated fully matching OEM standards without extra trimming during installation. Extra tests including pressure pulse inspection and oil vapor soaking aging test are added to eliminate leakage risks.
The whole production procedure from raw material sorting, molding to manual recheck follows standardized workshop management to balance mass output and consistent product quality. With reliable manufacturing capacity of Huaxiang, Honya supplies this premium Mercedes hose to overseas partners, helping global auto dealers source dependable parts for M274 ventilation system repair, and wins lasting customer trust with stable durability.
