OE 06E103547AC Oil-Water Separator High-Temperature Resistant Crankcase Ventilation Valve with Direct Bolt-On Installation

This Oil-Water Separator with OE numbers 06E103547AC and 06E103547AH is a critical crankcase ventilation part for Audi Q7 3.0T, Porsche Cayenne 3.0T and Volkswagen Touareg 3.0T. It separates oil mist from blow-by gas inside the crankcase, returns lubricating oil back to the oil pan, and guides purified gas into the intake system for secondary combustion. A defective separator often causes excessive oil consumption, blue exhaust smoke, whistling sound, rough idle and carbon buildup on intake components.

Constructed with high-temperature resistant reinforced plastic housing and optimized internal filtering structure, it maintains stable separation performance under repeated heat cycles and pressure fluctuations. Manufactured strictly to original OE specifications, it ensures precise fitment and direct bolt-on installation without extra modification. Every unit undergoes strict sealing and pressure testing before shipment. It is a reliable aftermarket replacement widely favored by auto repair shops and auto parts distributors.
