The koyo radiator fit great! Great quality and great finish too. I had a mishimoto on my rx8, and I will choose koyo every time from now on. The koyo fit like OEM. Make sure to get an aftermarket radiator cap because the OEM cap won't fit.

Great looking and functioning product. I was really shocked by the quality of this product, which made for a very easy install. I would recommend this to anyone looking to upgrade their cooling system.
