1 pair of silicone replacement heater core hoses for all 1990+ 300ZX models. Includes 4 new clamps.

These (2) hoses 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. We recommend replacing the stock rubber hoses which are often in poor condition and prone to rupturing anytime the engine is out or the heater core is being changed. 

5 ply reinforced high quality silicone hoses, 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!

Z1 Motorsports offers a full line of silicone hoses for the Z32 that will be the last hoses you will ever have to purchase. They will outlast the car at a comparable cost to new OEM replacements! There's no reason to consider anything else.

Sold individually.
