The Genuine 12261-28030 Crankcase Breather Hose is an OEM ventilation hose designed for Toyota vehicles. This genuine Toyota part plays a critical role in your engine's positive crankcase ventilation (PCV) system by routing blow-by gases and oil vapors from the crankcase to the intake manifold where they can be safely burned during combustion.

Key Features:

• Genuine Toyota OEM part ensures perfect fit and reliable performance
• Prevents pressure buildup in the crankcase that can lead to oil leaks and gasket failure
• Helps maintain proper engine efficiency and reduces harmful emissions
• Manufactured from durable, heat-resistant materials designed to withstand engine bay temperatures

Over time, breather hoses can become brittle, cracked, or clogged with oil residue, leading to problems such as rough idle, oil leaks, increased oil consumption, and poor engine performance. Regular inspection and replacement of worn breather hoses is essential for maintaining proper crankcase ventilation and preventing costly engine damage. This genuine Toyota replacement hose is engineered to exact OEM specifications for durability and long-lasting performance.
