Koyorad All-Aluminum Racing Radiator

Koyorad All-Aluminum Racing Radiator - Toyota GR86 / Subaru BRZ / FR-S (2013+)

Maximum Heat Dissipation & Bulletproof Track Reliability

Take your cooling system to the professional level with the Koyorad All-Aluminum Radiator. Engineered for the demanding thermal loads of the ZN/ZD chassis, this radiator features Koyorad’s proprietary 36mm "Hyper Core." This design offers a significant increase in cooling capacity over the factory unit without requiring modifications to your fan shroud or engine bay. Every radiator is hand-TIG welded and Nocolok brazed to ensure a leak-proof finish that can handle the high pressures of competitive driving. Whether you are running a naturally aspirated track build or a forced-induction street car, this radiator is the foundation of a reliable cooling system.

What’s Included in the Box:

- Koyorad All-Aluminum Radiator: (1) Full-replacement 36mm Hyper Core assembly.

- Magnetic Drain Plug: Included to capture any metallic particles in the cooling system.

- Factory Mounting Points: All brackets are pre-installed for a direct-fit installation.

The Koyorad Advantage

- 36mm Hyper Core Technology: Features a high-density fin and tube pitch that maximizes surface area, providing up to 40 percent more cooling efficiency than the thin, single-row OEM radiator.

- Precision TIG Welding: Hand-welded end tanks replace the factory plastic units, eliminating the risk of "tank separation" or cracking under high-pressure conditions.

- Nocolok Brazing Process: This specialized manufacturing process creates an incredibly strong bond between the tubes and fins, ensuring maximum heat transfer and structural integrity for the life of the car.

- OE-Spec Fitment: Designed as a "drop-in" replacement. It retains all factory mounting points for the fan shrouds, AC condenser, and coolant hoses, making installation straightforward.

- Mirror-Polished Finish: Adds a high-end, technical look to your engine bay while providing superior corrosion resistance compared to untreated aluminum.

- Cross-Generation Compatibility: Engineered to fit both the 1st Generation (2013-2021) and 2nd Generation (2022+) models, making it a versatile choice for any 86 or BRZ owner.

Precision Tip: When upgrading to a high-capacity radiator, we highly recommend using a high-quality coolant like Subaru Super Blue or Toyota Pink. For the 2nd Gen models, pairing this radiator with the Koyorad Billet Filler Neck (FN3037) and a high-pressure radiator cap is the ultimate way to "bulletproof" your cooling system. After installation, ensure you use a spill-free funnel to properly "burp" the system of air bubbles, as the Boxer engine is sensitive to air pockets in the coolant path.
