Rough Idle or Vacuum Leaks?

Replace Your Cracked 1.8T Breather Hose Before It Causes Bigger Problems.

The factory VW/Audi 1.8T crankcase breather hose is exposed to constant engine heat, oil vapor, and vacuum pressure.

Over time, the plastic and rubber sections become brittle, crack, and begin leaking vacuum and oil vapors.

A failing breather hose may cause:

✔ Rough idle
✔ Vacuum leaks
✔ Oil smell from engine bay
✔ Lean condition fault codes
✔ Check engine light
✔ Excessive crankcase pressure
✔ Oil residue around the engine

This OEM-style crankcase breather hose assembly is designed to restore proper PCV and crankcase ventilation system performance on VW/Audi 1.8T engines.

Manufactured from durable heat-resistant automotive-grade materials, it provides reliable vacuum sealing and direct-fit installation.
