This Silicone Rear PCV Hose for the 1990-1996 Nissan 300zx replaces the OEM rubber hose Located on back LH side of the engine, this hose connects to the metal elbow in the rear of the far LH "exhaust" valve cover, and delivers any excess crankcase pressure towards the PCV valve mounted under the RH side of the intake plenum. This hose is a 4 ply reinforced high quality silicone hose and is custom formed for perfect fitment on the Z32.
This is the last rear PCV hose you will ever need. Unlike conventional stock rubber hoses that deteriorate over time, dry rot, and ultimately crack this silicone hose will stay soft and never degrade. Best of all it costs less than a new OEM rubber hose.
