CSF Porsche 996 Turbo / GT2 / GT3 / 997 Turbo / GT2 (Left) All-Aluminum Radiator

With over five decades of specialized expertise in radiator manufacturing, CSF stands as a trusted leader in high-performance cooling solutions. The CSF Porsche 996 Turbo / GT2 / GT3 / 997 Turbo / GT2 (Left) All-Aluminum Radiator exemplifies this legacy, engineered to deliver superior cooling performance essential for maintaining optimal engine temperatures under demanding conditions. Whether for spirited street driving or rigorous track use, this radiator is designed to meet the exacting standards required by high horsepower builds and competitive motorsports applications.

At the core of this radiator’s advanced design is CSF’s proprietary B-Tube Technology, a significant innovation that enhances thermal efficiency beyond conventional standards. Unlike traditional oval “O” shaped tubes, CSF’s B-shaped tubes are meticulously formed and seam-brazed to create a robust, leak-resistant structure. This design allows the use of thinner and lighter aluminum materials without compromising strength, resulting in improved heat dissipation. The unique B-Tube configuration increases the heat transfer surface area by approximately 15% compared to standard tubes, effectively doubling the cooling efficiency within the same spatial constraints. This technology facilitates dual liquid laminar flow, optimizing coolant movement and heat exchange for superior engine temperature control.

Complementing the B-Tube core is an ultra-efficient multi-louvered fin design, precisely aligned to maximize airflow through the radiator. Each fin’s height and spacing—6.5mm in this model—are carefully engineered and validated through rigorous wind tunnel testing to ensure maximum heat rejection. This meticulous attention to detail guarantees that the radiator performs reliably under the most challenging thermal loads.

The CSF 996/997 radiator is engineered as a true “drop-in” replacement, ensuring seamless integration with existing vehicle components. All mounting brackets are CNC machined and welded to exacting tolerances, providing exceptional durability and a perfect fit without the need for modifications. The inlet and outlet connections replicate original equipment specifications, allowing the use of OEM or aftermarket hoses without compatibility issues. This design philosophy underscores CSF’s commitment to delivering products that combine ease of installation with uncompromising performance.
