034Motorsport Breather Hose Kit – Mid-AMB Audi A4 & Late-AWM Volkswagen Passat 1.8T Reinforced Silicone - 034-101-3004

034Motorsport Breather Hose Kit – Mid-AMB Audi A4 & Late-AWM Volkswagen Passat 1.8T
Reinforced Silicone - 034-101-3004

This complete silicone hose kit is designed to replace all of the crumbling plastic and rubber components that make up the factory breather hose system. Over time, the OEM breather components become brittle and prone to cracking, leading to vacuum leaks, oil vapour issues, and reduced engine reliability.

This kit fits 2003 B6 Audi A4 1.8T models with the AMB engine code (VIN range 8E-3-040000 to 8E-3-500000), as well as 2003–2005 Volkswagen Passat 1.8T models with the AWM engine code. It includes all hardware required to retrofit to a much simpler and more reliable breather system design.

All critical breather hoses are replaced with high-quality reinforced silicone, and the factory PCV valve is upgraded to a 034Motorsport billet aluminum PCV valve for improved durability and long-term performance.

A billet aluminum block breather adapter with an O-ring seal is included, utilizing the factory retaining clip, along with a cap/plug to eliminate and bypass the auxiliary check valve hose.
