Description

The Rein Crankcase Breather Hose is a component of the positive crankcase ventilation (PCV) system. It funnels pressurized air from the engine crankcase to the air/oil separator (PCV valve). This OE-quality hose is made in France and is a direct replacement for the original part.

A common failure point, this hose is crucial for engine performance and emissions compliance. Symptoms of a failing hose include cracks, breaks, leaks, broken connectors, and the Check Engine Light.
