Genuine 996-107-147-59 Vent Line for Oil Separator Lower Fitting

The Genuine 996-107-147-59 Vent Line is a factory-original crankcase ventilation hose designed for Porsche 996 and 986 models. This lower fitting vent line connects to the oil separator system on 996 models from 1999-2005, managing crankcase pressure and preventing oil leaks by routing blow-by gases through the air-oil separator.

Key Features:

• Genuine Porsche OEM quality for precise fitment and durability
• Lower fitting configuration for oil separator connections
• Heat-resistant construction to withstand engine compartment temperatures
• Critical component of the crankcase ventilation system
• Direct replacement for worn or cracked breather hoses

This vent line is essential for proper engine breathing and oil separator function. Over time, these hoses can become brittle and crack due to heat cycling, leading to vacuum leaks and rough idle. Replacing failed breather hoses with genuine Porsche parts ensures proper system operation and prevents oil misting in the engine bay.
