High-Capacity Cooling for High-Horsepower Builds

When your Subaru WRX or STI is tuned for maximum power, factory cooling systems often fall short. The CSF 42mm High-Performance 2-Row Aluminum Radiator is designed to handle the extreme heat generated by high-horsepower engines. With a 42mm core thickness, this unit provides significantly more fluid capacity and surface area than the OEM radiator.

Advanced Cooling Features

• 2-Row 42mm Core: Massive increase in cooling capacity, ideal for track days, autocross, and high-boost street applications.
• B-Tube Technology: CSF’s signature B-tube design improves heat transfer efficiency by 15% over standard radiator tubes.
• All-Aluminum Construction: Fully welded and brazed for superior strength and longevity compared to plastic-tank radiators.
• Direct Fitment: Engineered specifically for the 2008-2015 Subaru Impreza WRX and STI, ensuring a seamless installation without modifications.

This radiator is the ultimate insurance policy for your engine. By maintaining lower coolant temperatures, you reduce the risk of heat soak, allowing your engine to maintain peak timing and power output consistently. The robust aluminum construction is built to handle the vibration and thermal expansion cycles of high-performance driving. Whether you are building a dedicated track weapon or a high-performance daily driver, this CSF radiator is a critical component for engine longevity. Trust GGCRACING to deliver the cooling performance your Subaru deserves.
