CSF Porsche 991.2 911 / GT2 / GT3 / 718 Boxster/Cayman (Left) All-Aluminum Radiator

With over five decades of expertise in radiator manufacturing, CSF stands as a benchmark of quality and innovation in automotive cooling solutions. The CSF Porsche 991.2 911 / GT2 / GT3 / 718 Boxster/Cayman (Left) All-Aluminum Radiator exemplifies this legacy, engineered to deliver superior cooling performance for both street and track applications. This radiator is specifically designed to meet the rigorous demands of high horsepower builds and professional motorsports, ensuring optimal engine temperatures under the most challenging conditions.

The core of this radiator features a 2-row, 42mm design incorporating CSF’s exclusive B-Tube Technology. Unlike conventional oval-shaped "O" tubes, CSF’s B-tubes are meticulously engineered in a distinctive "B" shape, which are then brazed over the seam to create a robust, leak-proof seal. This innovative structure allows the use of thinner, lighter aluminum material without compromising strength, resulting in enhanced cooling efficiency. The B-tube design increases the heat transfer surface area by approximately 15% compared to traditional tubes, effectively combining the cooling capacity of two smaller tubes within the same spatial constraints. This dual liquid laminar flow optimizes thermal exchange, contributing to superior heat dissipation.

Complementing the B-tube core, the radiator is equipped with ultra-efficient multi-louvered fins, precisely aligned to maximize airflow through the core. Each fin is engineered with a 6.5mm height and a multi-louvered design to increase surface area contact, thereby enhancing heat rejection efficiency. These specifications are rigorously tested in CSF’s state-of-the-art wind tunnel laboratory to ensure peak performance under real-world conditions.

Installation of the CSF 991.2 911 / 718 radiator is straightforward, featuring a true "drop-in" fit that requires no modifications. The radiator’s OE-style brackets are CNC machined and welded to guarantee exceptional durability and precise fitment. Inlet and outlet connections are designed to match original equipment specifications, allowing seamless integration with OEM or aftermarket hoses. Additionally, this radiator supports the installation of OEM air conditioning condensers and fan shrouds, maintaining factory compatibility and functionality.
