These Silicone Heater Core Hoses for the 1990-1996 Nissan 300zx replace the OEM Rubber hoses that carry coolant between the metal inlet and outlet tubes on the heater core that stick out of the firewall to the metal tubes on the back of the motor on all Z32 models. These are 4 ply reinforced high quality silicone hoses and are custom formed for perfect fitment on the Z32.
These are the last heater core hoses 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 they cost less than new OEM rubber hoses!
