High quality ventilation duct 06C103217C for A4 S4

High-quality crankcase ventilation duct with OE number 06C103217C is specially designed and produced for Audi A4 and S4 series models, fully matching the original installation size, pipeline radian and interface caliber, enabling direct plug-and-play replacement without any cutting, grinding or auxiliary sealing accessories during vehicle maintenance. The main body of the ventilation pipe adopts upgraded glass fiber reinforced high-temperature resistant composite plastic raw material, which can resist the continuous high-temperature radiation from the engine cylinder head and exhaust pipeline all year round, and will not experience hardening, embrittlement, deformation or cracking after long-term use under high-temperature working conditions, completely solving the short service life defect of ordinary plastic ventilation pipes on the market. The built-in integrated sealing rings at both ends are made of high-performance fluororubber material with special oil-resistant formula, which can resist the erosion of high-temperature engine oil vapor and crankcase waste gas, keep the interface sealing tight for a long time, effectively prevent the leakage of crankcase pressure and oil gas seepage. This ventilation pipe plays a key role in balancing the internal pressure of the crankcase. When the original ventilation duct is aging, cracked or blocked, it will cause unstable crankcase pressure, resulting in a series of vehicle faults such as obvious engine idle jitter, abnormal increase of oil consumption, weak throttle response, and illuminated engine fault indicator light. After replacing our standard ventilation duct, the crankcase circulation system can return to normal working state, greatly reduce engine oil loss, stabilize idle speed and improve overall power performance. Every finished ventilation duct will go through strict multi-process testing before leaving the factory, including high-low temperature cycle aging test, full air tightness detection, pipeline tensile fatigue test and oil immersion corrosion test, all inspection standards refer to OEM factory requirements to ensure consistent stable quality of each batch of goods. We provide one-stop bulk procurement service for global auto parts wholesalers and professional VAG repair garages, with sufficient permanent spot inventory, flexible minimum order quantity and complete after-sales guarantee system, which can meet the long-term large-volume supply demand of overseas merchants for Audi chassis engine accessories.
