Best OEM Replacement

I had to replace my stock radiator after 10 years due to a leak. Got this installed with zero issues at my dealership, temps are lower than stock and the quality is superb. I paired this with IAG upper/lower radiator hoses and it all just dropped in no fuss.

100% recommend if you live in hot climates or a better than stock OEM drop in upgrade.

FYI the Subimods vehicle match tool is incorrect on the fitment for this part; it DOES support a non-STI WRX model. I have a 2015 WRX Premium (Non-STI) and it is 100% supported. Best to check the model on the Koyorad site directly for proper verification.

Thank you for your 5 Star Review! You are absolutely right — OEM does not last forever. Great call on choosing the Koyo Aluminum Racing Radiator as your upgrade!

Regards,

Great radiator.

Super easy install, I have mishimoto upper and lower hose and they fit better than the OEM radiator. Also worked perfectly with the mishimoto fans. Bleeding the coolant was a dream and my coolant runs cooler on average.

Hello,

Thank you for your 5-Star Review and added pic! The Koyo Aluminum Racing Radiator is a fantastic upgrade, and it is great to hear it paired well with your Mishimoto hoses and fans. Enjoy the cooler temps and improved cooling efficiency!
