The R3 specific Koyorad has an increased core thickness compared to the standard version for the earlier RX-8 (36mm core). The R3 RX-8 has a different design to the earlier Series 1 RX-8 this means that most aftermarket options will not fit. This is where Koyorad’s R3 specific radiator steps in to the limelight.

With cooling being so important to rotaries why not look at upgrading your cooling system. a Koyorad can aid in dropping your coolant temps significantly. Their high quality aluminium construction and OEM fitment means your not paying to have it modified (like many cheaper “racing” radiators)

The KOYO R-Series Core radiator provides improved cooling coverage for both street and track applications combined with show quality looks and finish

Construction is held to tight quality control standards that are illustrated in the outstanding Heliarc soldering, pristine tube and fin alignment, and mirror-like surface finish. The tubes, fins, headers, and brackets are brazed in a state-of-the-art Nocolok furnace, which bonds these components into a virtually indestructible radiator unit.


All fan mounts are situated to OE specifications, and using the OEM mounting locations facilitates fitment into the RX-8.
Why not include a set of SFS Performence Radiator hoses with your new cooling upgrade

Suitable for 2008-2013 RX-8 R3 models with Manual transmission only
