Competition Spec All Aluminum Radiator

When maximum cooling performance is the priority, the Koyorad Hyper Core Competition Radiator is the ultimate solution for the 2022+ Toyota GR86 and Subaru BRZ. Designed specifically for high-horsepower builds, endurance racing, drifting, and demanding track use, the Competition Spec features Koyorad's largest 48mm high-density Hyper Core, delivering exceptional heat dissipation and cooling efficiency even under the most extreme driving conditions. It offers a 13% thicker core than the standard Hyper V-Series radiator for even greater cooling capacity.

Constructed from hand-welded, furnace-brazed aluminum, the Competition Radiator replaces the factory plastic end tanks with a durable all-aluminum design built to withstand repeated heat cycles and the demands of motorsport. A GR86/BRZ-specific internal partition design optimizes coolant flow throughout the core, while integrated thermal reliefs allow the radiator to expand and contract during heat cycling, reducing stress and improving long-term durability.

Despite its increased capacity, the Hyper Core Competition Radiator remains a true plug-and-play, bolt-on upgrade, retaining the factory fan shroud and mounting locations with no cutting, fabrication, or additional components required. Whether your car is naturally aspirated, turbocharged, or supercharged, this radiator provides the cooling headroom needed to keep temperatures under control during the most demanding conditions.

For the ultimate cooling system upgrade, we highly recommend pairing this radiator with the Koyorad High Pressure Aluminum Filler Neck. The factory plastic filler neck is known to become brittle after repeated heat cycles, while the Koyorad aluminum replacement offers increased durability, improved reliability, and complements the all-aluminum construction of the radiator for a complete OEM+ cooling system.
