Why Upgrade to a Koyo Aluminum Radiator?
Factory plastic radiators crack under stress. Upgrading to a Koyo aluminum racing radiator delivers maximum heat dissipation, increased coolant capacity, and rugged durability for street and motorsport use.
Our Koyo Cooling Range Includes:
- Performance Radiators – Direct-fit units for Nissan, Toyota, Honda, Subaru, and Mitsubishi.
- Koyo Oil Coolers – High-efficiency cores to keep engine and transmission oil temperatures safe.
- Koyo Hyper Caps – High-pressure 1.3 Bar racing caps to prevent system boil-overs.
Available in core thicknesses from 25mm to 53mm. Browse our vehicle subcategories below for competitive online pricing and fast nationwide delivery across NZ.
