This PCV hose connector (11821AA660) is a key component of the positive crankcase ventilation (PVC) system of your vehicle. This connector controls the flow of gases from the crankcase to the intake manifold. By having a smooth exchange of gases between these parts, your engine can function more efficiently.

This valve can also help reduce the amount of harmful gases from your emissions. The excess gases are directed to the intake manifold for engine reuse instead of getting expelled from your exhausts. This process gives your engine more power while reducing the harmful emissions coming from your ride. 

This valve is also essential in keeping your engine running smoothly. If the excess gases aren’t rerouted to the intake manifold, they can mix with the motor oil in the crankcase. When this happens, it produces sludge that can clog and erode your engine, causing it to run rough, waste fuel, or fail altogether.
