Construction & Design:

Koyo radiators are manufactured in privately owned facilities in Japan, allowing strict quality control throughout the entire production process. Each radiator core is hand-assembled using the highest grade aluminum, then Nocolok brazed and TIG welded by skilled technicians to ensure durability and leak-free performance. The all-aluminum construction not only reduces weight compared to traditional plastic tanks but also improves thermal conductivity, resulting in faster and more efficient heat dissipation.

The polished mirror finish not only enhances corrosion resistance but also adds a clean, professional look under the hood. The integrated accessory fitting provides flexibility for enthusiasts who want to monitor coolant temperatures with aftermarket gauges.

Installation & Fitment:

This Koyo Aluminum Radiator is designed as a direct-fit replacement for the Scion FR-S (2013–2016), Toyota 86 (2017–2020), and Subaru BRZ (2013–2020), fitting both automatic and manual transmission variants. It mounts directly to the factory fan shroud and uses existing mounting points, making installation straightforward without the need for modifications or additional brackets.

Installation can typically be completed with basic hand tools and standard mechanical knowledge. The included accessory fitting allows easy integration of temperature sensors if desired.

What's Included:
