Mishimoto MMRAD-RSX-02 Performance Aluminum Radiator, Compatible with Acura RSX, 2002-2006

Amazing product and a great replacement over the stock radiator. Like many RSX owners, my facotry radiator cracked (at the top plastic section), so upgrading to a mishimoto was a win-win scenario since an OEM radiator is incredibly expensive. The installation was pretty basic. I did run into some issues with a leak near the bottom radiator hose, but I got that fixed and everything works flawlessly.

Though made for rsx i had to replace older radiator due to damage and it was bowed i opted for mishi aluminum rad considering price difference from replacing with OEM denso was not to significantly different and im glad i did the difference is noticible and having to add a trans cooler has improved the vehicles drive and acceleration dramatically

Mishimoto really does make nice stuff. The packaging was very nice foam covering every inch of it and the finish and attention to detail far exceeded my expectations. Every weld was consistent and even and it fit really well. No issues or modifications required to anything. It far exceeds the stock radiator in every aspect. The only thing I don like is in my car it's completely covered by the bumper and you can't see any of its beauty haha. Truly a great product. Will buy mishimoto again for other cars as I'm sure I won't need another for this car now.

Was in need of a new radiator since my stock RSX one was cracked. Ended up purchasing this mishimoto one. Product looked great as I took it out of the box. Day of installation I tried unscrewing the radiator fan switch plug but noticed it was getting very hard to unscrew. Finally after unscrewing it I noticed that half of the outer threads on the radiator for the fan switch were completely stripped. I had to retap the first half of the threads because I needed the radiator and I couldn't wait for a replacement. Besides that everything seems to be working as it should so far.

I have this radiator in all 3 of my RSXs and in my 1993 Integra. Work great every time.

Bought to upgrade stock and this came in leaking. Unfortunately, waited a few weeks to drop it in and it was past the return date!

I'm very happy with this product. It was a great fit. All aluminum construction is superior to the OEM plastic. It was easy install and it's been working flawlessly.

Perfect direct fit (2005 RSX-S), everything lined up correctly. Very solid welds. I expect this radiator to last longer than the rest of the car.
