Genuine 079-133-424 S Intake Manifold Vent Pipe

The Genuine 079-133-424 S Intake Manifold Vent Pipe is an OEM replacement component designed for Audi's positive crankcase ventilation (PCV) system. This factory-engineered pipe connects the crankcase ventilation system to the intake manifold, allowing blow-by gases and crankcase vapors to be routed back into the engine for re-combustion rather than venting to the atmosphere.

Key Features:

• Genuine OEM part manufactured by Volkswagen/Audi for precise fit and compatibility
• Direct replacement for worn, cracked, or damaged intake manifold vent pipes
• Essential component of the positive crankcase ventilation system
• Helps maintain proper crankcase pressure and prevents oil leaks
• Ensures compliance with emissions standards by recycling crankcase gases
• Constructed from durable materials designed to withstand engine heat and pressure cycles

This intake manifold vent pipe plays a critical role in engine health by managing crankcase pressure and preventing harmful blow-by gases from escaping. A failed or leaking vent pipe can cause rough idle, excessive oil consumption, oil leaks from seals and gaskets, and improper fuel trim readings. Regular inspection and replacement of worn crankcase ventilation components helps maintain engine efficiency and prevents costly damage.
