Hyper-V Series All Aluminum Radiator

For enthusiasts who demand the absolute best cooling performance, the Koyorad Hyper Core Competition Radiator is the flagship solution for the 2022+ Toyota GR86 and Subaru BRZ. Building upon the proven Hyper V-Series platform, the Competition Spec radiator features a 48mm high-density Hyper Core—a 13% increase in core thickness over the standard Hyper V radiator—to deliver maximum heat dissipation for high-horsepower builds, endurance racing, drifting, and demanding track use.

Constructed from hand-welded, furnace-brazed aluminum, the Competition Spec replaces the factory plastic end tanks with a fully aluminum design built to withstand the extreme temperatures and repeated heat cycles encountered in motorsports. An all-new GR86/BRZ-specific internal partition design optimizes coolant flow throughout the core, while strategically placed thermal reliefs allow the radiator to expand and contract during heat cycling to resist warping and improve long-term durability.

Despite its increased capacity, the Hyper Core Competition Radiator remains a true bolt-on upgrade, retaining the factory fan shroud and mounting locations with no cutting, fabrication, or additional components required. Whether your GR86 or BRZ is naturally aspirated, turbocharged, or supercharged, this radiator provides the cooling capacity needed to maintain consistent engine temperatures 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 aluminum filler neck replaces the factory plastic unit with a stronger, more durable design that is better suited for repeated heat cycles and high-performance driving. Together, the Koyorad radiator and filler neck create a complete OEM+ cooling solution that improves both reliability and long-term durability.
