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

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.

bought this back in jan '21 and have had no issues since then. install flawless, no fitment issues, and no leaks whatsoever. will be purchasing another one since i had a accident in november '24 and need to get a new one :( one thing i will note is the oem thermostat takes a while to open up during warmup since this radiator holds more liquid than the oem radiator

It’s been 5 years and this baby is still going strong.

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

A MUST HAVE! bought this mishimoto radiator to replace my failing OEM radiator, this is completely worth buying, to make it even more worth the buy is to also buy the shrouded fans.

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.

It works perfectly. Only reason I give it 4 stars is because the fitment isn't exact. One of the fan screw holes doesn't line up as well as on the bottom where it rests. Also the top mounts are a bit off but they do go in with a bit of force. The whose to the reservoir sits a bit higher than stock but not a big deal. Other than those minor issues it's an excellent oem replacement.

Greats fit an Acura RSX 2002

Bought this to replace my leaky OEM rad. Build quality seems great, has OEM fit which makes for an easy install. Will buy Mishimoto if I need to replace another.

Car died couple days after

Good product but the seller is a nightmare.
