This set of silicone hoses replaces the factory rubber heater core hoses found on all 2003-2006 Nissan 350Z and Infiniti G35 models equipped with a VQ35DE powertrain. These 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. Over time, the factory rubber hoses degrade and can burst from pressure and heat. Our silicone hoses are made from high-quality multi-ply reinforced silicone and custom formed for perfect fitment. These are the last hoses you will ever need. Unlike conventional stock rubber hoses that deteriorate over time, dry rot, and ultimately crack, silicone hoses will stay soft and never degrade.

Z1 silicone hose can be purchased in your choice of BLACK, RED, or BLUE. We also recommend replacing the coolant bleeder whenever servicing the heater hoses!

Benefits of Z1 Silicone:

• Exceptional thermal resistance prevents breakdown even at higher than normal operating temperatures.
• Superior flexibility when compared to rubber, making installation and service a breeze!
• Durable silicone material ensures these hoses will last as long as your truck.

Fits:

• 2003-2006 Nissan 350Z
