I bought this radiator a couple of months ago (on Amazon.com) and couldn't be more happy with it.

it was $212.64 or something and came with these two fans

But the fans could not fit in the space of my 1.6L engine. And there was no way to mount them.
So i just used the OEM fans and they fit great.

I also had to make custom brackets for the radiator to fit, but i'm almost positive the owner before me had broken a lot of pieces under the hood.

If your Miata is lowered i HIGHLY suggest putting a different drain plug on the bottom of the radiator, as it hangs pretty low. I had a buddy make a plug out of metal and put threads on it.

In closing i think this is a great priced radiator and the car has been running cooler since i've installed it (just over 1000 miles since being put on)

I suggest finding this radiator without the fans and i'm sure it'll be cheaper.
