This Silicone IAA inlet hose for the 1990-1996 Nissan 300zx replaces the OEM hose located on the top LH side of the Z32 motor that connects onto the inlet of the IAA (idle air adjustment unit) delivering air from the intake tract. This hose is 4 ply reinforced high quality silicone hose and is custom formed for perfect fitment on the Z32.
This is the last IAA inlet 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 considerably less than a new OEM rubber hose
