Key Features & Benefits

• Full Aluminum Core Construction — All-aluminum tanks and core replace the OEM plastic end tanks, delivering superior heat dissipation and long-term durability against cracking and warping under high-heat conditions.
• Increased Cooling Capacity — Thicker, high-density core increases coolant volume and surface area compared to the stock radiator, reducing operating temperatures during spirited driving and track sessions.
• Direct OEM Replacement Fitment — Engineered as a true plug-and-play replacement using factory mounting points and hose connections, eliminating the need for custom fabrication or modifications.
• TIG-Welded Construction — Precision TIG-welded seams ensure leak-free performance under high pressure and thermal cycling, far exceeding the reliability of crimped OEM plastic tanks.
• Pressure-Tested Quality Control — Every unit is pressure-tested before leaving the factory, ensuring zero defects right out of the box.
