Product Description

These silicone hoses replace the factory rubber radiator overflow (reservoir) hoses on all Nissan 370Z models. Over time, the factory rubber hoses degrade and can burst from pressure and heat, causing your car to overheat and leave you stranded. Our silicone hoses are made from high-quality multi-ply reinforced silicone and custom formed for perfect fitment. Unlike conventional stock rubber hoses that deteriorate over time, dry rot, and ultimately crack, silicone hoses will stay soft and never degrade. These are the last hoses you will ever need!

Z1 silicone hose can be purchased in your choice of BLACK, RED, or BLUE.

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:

  • 2009-2020 Nissan 370Z

Z1 offers a full line of custom-formed silicone hoses for your Nissan and Infiniti! CLICK HERE to shop the complete line of Z1 Silicone products.

Looks great, my old factory hoses were showing their age and starting to get chalky looking. These silicone replacements are much higher quality and should last much longer. Fitment is 99% the same as the OEM hoses, the radius on the bend immediately after the overflow nipple is slightly larger but it does not really affect the hose routing using the original attachment points.

Perfect fit, easy install, and looks great! Would have been 5 stars, but one of the “Z1” logos was on the bottom of the overflow hose, tucked behind the bumper where you can’t see it instead of the top where it could be seen.
