Koyo Aluminum Racing Radiator

The Koyo Aluminum Racing Radiator line is a series of all-aluminum performance replacement radiators. They are built to improve cooling efficiency and durability over stock units. Many factory radiators use plastic end tanks. Over many heat cycles those tanks can expand and eventually leak. An all-aluminum radiator helps avoid that problem, which makes it a good upgrade for street, track, and motorsport use.

Key Features:

• All-aluminum construction is more durable than OEM radiators with plastic tanks.
• Improved cooling efficiency comes from a core designed for better heat transfer and coolant flow.
• Precise tube and fin alignment promotes efficient heat transfer.
• Nocolok brazing bonds the tubes, fins, headers, and brackets. This helps them resist vibration, road debris, and the elements.
• Heli-arc (TIG) welding reinforces the aluminum connections. It also lets the radiator be welded and repaired in the future if it is damaged.
• Precision-machined billet filler neck adds durability.
• Direct-replacement design uses factory mounting locations, so installation is simpler.

Koyo (Koyorad) is known for performance cooling products. These radiators are offered in several core designs, including V-Core and Hyper-Core. The designs suit applications from space-limited engine bays to high-heat conditions. Please check each individual listing for the core design and options.
