Hot selling Oil Water Separator 04E103464AM for A3 S3

Hot selling oil water separator OE 04E103464AM is a highly demanded crankcase ventilation PCV module developed for Audi A3 and S3 with EA211 1.4 TSI turbocharged engines, and it is compatible with various MQB platform vehicles including Golf MK7, Tiguan and Audi A4 B9. All mounting hole spacing, pipeline interface diameters and internal labyrinth separation chamber layouts strictly follow OEM dimensional standards, supporting direct bolt-on installation without modifying valve cover assemblies or adding extra sealing gaskets during engine maintenance. The shell is injection molded with reinforced high-temperature resistant PA66 engineering plastic treated with anti-oil-corrosion coating, and internal multi-stage folded labyrinth channels efficiently trap fine oil mist particles mixed in blow-by gas, separating engine oil from waste gas and guiding condensed lubricant back to the crankcase steadily. Clogged original oil water separators lose oil-gas separation efficiency, causing excessive engine oil consumption, heavy carbon accumulation on throttle valves and intake manifolds, rough unstable idle speed, rising fuel consumption and persistent engine malfunction warning lights on the dashboard. Every finished separator undergoes air flow balance calibration, hydraulic tightness durability testing and long-term high-low temperature cyclic aging inspection under strict OEM quality standards to ensure consistent and reliable separation performance of each production batch. We offer one-stop bulk procurement services for global Volkswagen and Audi professional repair garages and cross-border auto parts wholesalers, maintaining abundant spot inventory all year round with flexible minimum order quantity and full long-term after-sales warranty to satisfy continuous large-volume purchasing needs of overseas partners.
