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