Genuine 11810AA141 OEM PCV Valve Positive Crankcase Ventilation Valve

The Genuine 11810AA141 is an OEM Positive Crankcase Ventilation (PCV) valve designed to factory specifications. As a direct-fit OEM replacement, this PCV valve restores proper crankcase pressure regulation, helping to reduce harmful emissions and protect engine internals from sludge buildup caused by blow-by gases.

The PCV valve is a critical component of the engine's emission control system. It routes combustion blow-by gases from the crankcase back into the intake manifold to be re-burned, rather than venting them into the atmosphere. A faulty or clogged PCV valve can lead to increased oil consumption, rough idle, oil leaks, and accelerated engine wear.

Key Features:

• Genuine OEM part — manufactured to exact factory specifications
• Direct replacement for the original PCV valve — no modifications required
• Ensures proper crankcase ventilation and pressure regulation
• Helps prevent oil sludge buildup and reduces harmful emissions
• Restores proper idle quality and engine performance
• Part Number: 11810AA141 (also referenced as 11810-AA141)

Choosing a Genuine OEM PCV valve ensures the correct fit, function, and longevity compared to aftermarket alternatives, maintaining the integrity of your vehicle's emission control and lubrication systems.
