Genuine 06B-103-221 M Crankcase Breather Elbow Hose Fitting

The Genuine 06B-103-221 M is an OEM crankcase breather elbow designed for Volkswagen and Audi vehicles equipped with the 1.8T engine. This essential engine ventilation component connects the crankcase breather system to the intake manifold, allowing positive crankcase ventilation (PCV) gases to be routed back into the engine for combustion.

Key Features:

• Genuine Volkswagen/Audi OEM part ensures precise fit and reliable performance
• Durable plastic construction designed to withstand engine heat and pressure
• Direct replacement for worn or cracked breather elbows
• Critical component for maintaining proper crankcase ventilation
• Prevents vacuum leaks that can cause rough idle and check engine lights

This breather elbow is a common maintenance item on 1.8T engines, as the plastic can become brittle over time from heat cycling. Replacing a faulty breather elbow helps restore proper engine performance and prevents unmetered air from entering the intake system. OEM part number 06B-103-221-M (also referenced as 06B103221M).
