PCV Hose Assembly - 11815AB213

The Positive Crankcase Ventilation (PCV) hose is a pivotal component in your Subaru's engine. It's designed to redirect harmful gases from the crankcase back into the combustion chamber to be burned off, thereby reducing emissions and preventing the build-up of sludge within the engine.

The PCV hose works by connecting the crankcase to the PCV valve, creating a passage for the crankcase gases to be evacuated and recycled. This process is not only vital for environmental conservation but also ensures optimal engine performance and longevity.
