Genuine 12261-37040 Pcv Hose

The Genuine 12261-37040 is an OEM positive crankcase ventilation (PCV) hose designed to maintain proper crankcase pressure and emissions control in your vehicle's engine. This factory-spec hose routes blow-by gases from the crankcase back into the intake system for reburning, helping to reduce emissions and prevent oil leaks caused by excessive crankcase pressure.

Key Features:

• Genuine OEM part ensures exact fit and reliable performance
• Constructed from durable materials resistant to oil, heat, and environmental conditions
• Maintains proper PCV system function for optimal engine performance
• Direct replacement for worn or cracked original hose
• Helps prevent rough idle, increased oil consumption, and failed emissions tests

A failing PCV hose can cause vacuum leaks, rough idle, and check engine lights. Replacing this critical emissions component with a genuine OEM hose ensures your vehicle maintains proper crankcase ventilation and passes emissions inspections. OEM Part Number: 12261-37040.
