### ⭐⭐⭐⭐⭐ $$$ but good.
*by D***S on 4 March 2026*

Fits my koyorad radiator perfectly. It's expensive but it's quality.

### ⭐⭐⭐⭐⭐ The koyo cap fits good looks great and doesn't leak
*by O***S on 16 September 2021*

I like the way the cap looks on the red I like the fact that it doesn't leak and I would recommend it for anyone who has a Koyo radiator

### ⭐⭐⭐⭐⭐ Does what it's supposed to, high quality part.
*by K***Y on 2 March 2020*

So far so good. Works as intended on my 07 350z. Good build quality. This is one of those kinds of parts that it either works well or it doesn't, this fits my car and does what it's supposed to. Highly recommend, I have a Koyo solid aluminum radiator too, so take that into consideration as well. Radiator is significantly better than the stock one as well, so I recommend that as well.
