Coore is the authorised Australian distributor for Koyo performance radiators — so when you buy here, you're getting genuine Koyo product backed by local stock and support.
The Koyo Hyper V-Core 36mm Series represents the pinnacle of Koyo's all-aluminium radiator lineup. Developed specifically for high-heat, space-constrained applications where factory inlet/outlet positioning rules out a conventional N-FLO design, the Hyper V-Core uses a specially engineered fin and tube pitch geometry that dramatically increases surface area without compromising airflow. The result is a radiator that runs cooler, fits cleaner, and outlasts the OEM unit — all with a direct bolt-in installation.

- 2003–2005 models: The filler neck on this radiator requires a specific radiator cap suited to 2003–2005 Forester XT applications — sold separately.
- Automatic transmission vehicles: Compatible, however an external transmission oil cooler is required — sold separately.
