Vent pipe on air filter for VOLKSWAGEN Combi Bay Window (08/1974-07/1979)

When an engine is running, a small amount of combustion gas can escape from the cylinders and pass through the piston rings. These gases, known as breather gases or oil vapors, must be vented through this rubber elbow hose to prevent pressure from building up in the engine, which could damage seals or internal components. Dimensions: 200 mm x 25 mm.
