This Silicone IAA to Air Regulator Hose for the 1990-1996 Nissan 300zx replaces the OEM hose located on the top back side of the motor that runs from the IAA idle air adjustment unit to the air regulator valve. 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 IAA to Air Regulator 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
