Koyo R1443N Mazda 93-95 RX-7 FD3S Turbo MT N-FLO (Dual Pass) Aluminum Radiator

This radiator is likely the best you can find. The quality on the Koyo will exceed the Mishimoto and it's known amongst RX-7 enthusiast to be even better than the more expensive Fluidyne. The cooling is top notch and will help to permanently solve your cooling issues in the FD RX-7. The only issue is the fitment. It's not easy to get in and will be tough to clear the AC condenser on a stock car and it gets even more difficult with the stock air box. I advise reading up on the install process on RX7club dot com to The effort is worth it though and it looks beautiful in the car. This is something every RX-7 should have in it.
