This is a direct replacement positive crankcase ventilation (pcv) valve, a crucial component for managing engine blow-by gases and maintaining internal pressure.
Its primary function is as a one-way check valve. It vents pressure from the crankcase into the intake manifold for reburning, while sealing to prevent reverse flow.
A properly functioning valve is key for engine longevity. It helps prevent oil sludge buildup, reduces excessive pressure that can damage seals, and supports lower emissions.
For correct fitment, please verify that one of the part numbers on your original valve matches those listed for this product: 111810EA200, 118106N202, 118106N201, or 1181-1KC0A.
You will receive one black and green pcv valve. Replacing a clogged or faulty valve with this part is a simple maintenance step that can contribute to smoother engine operation.
