Product Description
These silicone hoses replace the factory rubber radiator hoses on all Nissan 350Z and Infiniti G35 models equipped with the VQ35DE powertrain. 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:
- 2003-2006 Nissan 350Z
- 2003-2006 Infiniti G35 Sedan
- 2003-2007 Infiniti G35 Coupe
Does not fit '07-'08 G35 Sedan's. Hoses for those models can be found HERE.
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.

These look great on my 06 350z, much better than the factory rubber hoses. They give the Z a custom look under the hood. A+

I like them I needed to trim the upper hose for fitment and I wish the lower radiator hose had the same guard that the oem one has for the fan assembly but you can always make you own with the old hose so their's no risk of rubbing

The color really stands out. They fit fine other then the top radiator hose that I had to cut manually in order for it to fit my 350z. Looks a bit jagged and was looking for a nicer cut.

Had to modify the upper hose because it was to long and didn’t fit. Had to cut about half an inch off both ends of it. Other than that they are good quality and I’ll just have to see how long they last

Reused stock clamps on the two main radiator hoses. Had to use a different steel hose clamps for the other hose. These hoses were a perfect fit for my car without any modification needed.

The quality of hose is great, no complaints there. I just didn’t like that they weren’t cut to length, I had to cut but my upper and lower hoses because they were way to long and the lower was sitting against my ac compressor. I also wish they came with new clamps. The small hose would not fit in my stock clamps and the bigger ones barely fit. I just think for the price they could throw in some clamps. Plus it’ll make the engine look cleaner. Great hoses tho.

Very high quality, fits great on 2004 350z base model VQ35DE. Note that if you have the Mishimoto radiator you will need to trim like a half-inch or so from the top coolant hose. This specific hose was too long as it was intended for the OEM radiator which is MUCH thinner than the Mishimoto. But after trimming it up no issues at all, perfect fit. To trim it up put it on the car first to get an idea of how much you have to cut, and then just get a razor and shave it a little, reinstall to measure, repeat until good fit.
These hoses have been on for months now with no issues. Still strong and flexible, no leaking, etc. I definitely recommend them if you've got old faded and cracking hoses like I did.

Compared to the OEM rubber hoses these are much better quality and can literally tell the difference side by side. On a side note, my upper hose needed to be trimmed about 1/4 in an inch to fit properly, this could be due to the fact that I replaced my OEM radiator with an aftermarket OEM type and the neck could be a bit longer. Either way they look great and I also have piece of mind knowing they won't be leaking!

Perfect fit on my 05 G35X, feel much thicker than the OEM hoses and look really good too. I wish there was a silicone hose for the coolant overflow tank for the G35, but oh well.

These are a nice addition to any set up. They do add visual to the engine and seem to hold up well.
