CSF Left High-Performance Radiator for 997 Porsche 911 Carrera / GT3 RS [7047]

CSF Left High-Performance Radiator for 997 Porsche 911 Carrera / GT3 RS [7047]

With over five decades of expertise in radiator manufacturing, CSF delivers industry-leading solutions for superior engine cooling. The CSF High-Performance All-Aluminum Radiator is the ultimate choice for Porsche 997 911 and 987 Boxster/Cayman models, whether for street or track use. Essential for high-horsepower builds and motorsport vehicles, this radiator is engineered to meet the rigorous demands of performance applications. Featuring a 2-row core and CSF’s exclusive B-Tube Technology, this radiator stands apart from conventional designs. Unlike standard “O” tubes, the B-Tube design is carefully shaped and seam-brazed to enhance durability and cooling efficiency. This innovation enables the use of thinner, lighter aluminum while increasing the heat transfer surface area by approximately 15%, achieving the performance of two smaller tubes in the space of one. This design also facilitates dual liquid laminar flow for superior cooling. To maximize airflow and heat rejection, CSF incorporates ultra-efficient, multi-louvered fins, precisely aligned and rigorously tested in its wind-tunnel lab. Each fin is optimized for the specific application, ensuring peak performance in the most demanding environments.

HIGH EFFICIENCY MULTI-LOUVERED FINS

• CSF incorporates ultra-efficient multi-louvered fins, precisely aligned to optimize airflow through each radiator core. Fin specifications are meticulously measured and tailored for each application, undergoing rigorous testing in CSF’s wind-tunnel lab to ensure maximum heat rejection efficiency.

CSF’S EXCLUSIVE B-TUBE TECHNOLOGY

• CSF utilizes a specially engineered “B-Tube” design instead of the conventional oval-shaped “O” type radiator tube. These “B-Tubes” are carefully crafted and brazed over the seam to ensure a secure seal. This innovative design allows CSF to employ thinner, lighter aluminum materials while achieving superior cooling efficiency, as the “B-Tubes” are stronger than traditional welded “O” shape tubes. By incorporating a seam-brazed middle section, the “B-Tube” design increases the heat transfer surface area by approximately 15% compared to standard tubes. This configuration delivers the performance of two smaller tubes within the space of one, providing enhanced “dual liquid cooling” efficiency.
