034Motorsport Breather Hose – Audi B5 A4 1.8T AEB Manual, Block to Intake Manifold Reinforced Silicone - 034-101-3025

This fully reinforced silicone breather hose is designed to replace the crumbling and leaking OEM rubber hose found on B5 Audi A4 1.8T models with the AEB engine and manual transmission. This hose runs from the bottom of the intake manifold to the check valve attached to the lower block breather hose and is a common failure point that can cause boost and vacuum leaks.

Manufactured from high-quality automotive-grade silicone, this hose provides long-term durability and superior resistance to heat, oil vapour, and ageing compared to the factory rubber component.
