Heat-Resistant Rubber Composite Crankshaft Ventilation Pipe Air Tightness Tested Crankcase Breather Hose with Direct Plug-In Installation

This crankshaft ventilation pipe with OE number 03H103202D is a reliable aftermarket replacement part designed for Audi Q7, Volkswagen Touareg, EOS and Skoda Superb. It is produced to match OEM dimensions and standards, ensuring precise fitment and seamless connection for the engine crankcase ventilation system.

This pipe is an essential part of the PCV system. It guides blow-by gas from the crankshaft back into the intake manifold for secondary combustion, preventing excess pressure buildup inside the crankcase. If the pipe cracks, hardens or leaks, it will cause oil leakage, rough idle, whistling noises and increased oil consumption. In severe cases, it may trigger engine warning codes and damage related seals and gaskets.

Made of high-performance heat-resistant rubber composite material, it resists aging, oil corrosion and high-temperature cycles under the hood. It maintains good flexibility and sealing performance even after long service in harsh engine bay environments. Each unit passes air tightness inspection before shipment to avoid leakage risks.

It supports direct plug-in installation with no cutting or adjustment required, lowering labor cost for workshops. Suitable for auto repair shops, spare parts wholesalers and aftermarket retailers. It is an economical and dependable option to fix crankcase ventilation faults and protect the engine for these VAG models.
