The Silicone Air Regulator to Balance Tube Hose for the 1990-1996 300zx replaces the stock rubber hose located on the top back side of the motor that runs from the air regulator valve to the balance tube. It is a 4 ply reinforced high quality silicone hose and is custom formed for perfect fitment on the Z32.
This is the last balance tube 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 hose!
