Mustang PCV Hose Rear of Intake Manifold 1987-1993
PCV Hose at the Rear of the Intake Manifold for 1987-1993 Mustangs.
As with most hoses, PCV hoses can become brittle as they age. This hose runs from the rear of the intake manifold to under the center of the upper intake manifold. It relieves excess crankcase pressure by letting the air circulate back through the intake system.
