CSF Porsche 997 911 / GT3 / 987 Boxster / Cayman (Right) All-Aluminum Radiator

With over five decades of dedicated expertise in radiator manufacturing, CSF stands as a premier choice for maintaining optimal engine temperatures in Porsche 997 911, GT3, and 987 Boxster/Cayman models. The CSF High-Performance All-Aluminum Radiator (Right) is engineered to deliver superior cooling performance, whether on the street or the racetrack, ensuring your vehicle operates at peak efficiency under all conditions. This radiator is meticulously designed with a 2-Row core incorporating CSF’s exclusive B-Tube Technology. Unlike conventional oval-shaped “O” type tubes, CSF’s innovative “B-tubes” feature a unique cross-sectional design that enhances structural integrity and cooling efficiency. Each tube is precisely formed and seam-brazed, allowing the use of thinner, lighter aluminum material without compromising strength. This advanced design increases the heat transfer surface area by approximately 15% compared to traditional tubes, effectively providing the cooling efficiency of two smaller tubes within the same spatial constraints. The dual liquid laminar flow enabled by the “B-tubes” further optimizes heat dissipation, a critical factor in high-performance and motorsport applications. Complementing the tube design, CSF employs ultra-efficient multi-louvered fins that are carefully aligned to maximize airflow through the radiator core. Each fin specification is meticulously calculated and validated through rigorous wind-tunnel testing to achieve maximum heat rejection efficiency. This attention to detail ensures that the radiator not only meets but exceeds the demanding cooling requirements of high-horsepower and race vehicles. The CSF radiator offers a true “Drop-in fit” installation, requiring no modifications to the vehicle. The OE-style brackets are CNC machined and welded to guarantee exceptional durability and precise fitment. Inlet and outlet connections are engineered to match original equipment manufacturer (OEM) specifications, allowing seamless integration with existing OEM hoses or compatible aftermarket components. This design consideration simplifies installation and maintains the integrity of the vehicle’s cooling system.
