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

With over five decades of expertise in radiator manufacturing, CSF stands as a leader in delivering high-performance cooling solutions. The CSF Porsche 991.2 911 / GT2 / GT3 / 718 Boxster/Cayman (Right) All-Aluminum Radiator exemplifies this legacy, engineered to maintain optimal engine temperatures under the most demanding conditions. Whether for street use or competitive motorsports, this radiator is a critical component for high horsepower builds and race vehicles requiring enhanced cooling efficiency.

At the core of this radiator’s superior performance is CSF’s exclusive B-Tube Technology, integrated within a 2-row, 42mm core design. Unlike traditional oval "O" shaped tubes, CSF’s innovative "B" shaped tubes are precision-formed and seam-brazed to ensure structural integrity. This construction allows the use of thinner, lighter aluminum material without compromising strength, resulting in improved heat dissipation. The unique inlet placement in the middle of the tube increases the heat transfer surface area by approximately 15% compared to conventional tubes, effectively doubling the cooling efficiency within the same spatial constraints.

The B-Tube design facilitates dual liquid laminar flow, optimizing coolant movement through the radiator for maximum thermal exchange. Complementing this, CSF employs ultra-efficient multi-louvered fins, meticulously aligned to maximize airflow through the core. Each fin specification is carefully engineered and validated through rigorous wind-tunnel testing to ensure peak heat rejection performance.

Designed as a true “drop-in fit” replacement, the CSF radiator requires no modifications for installation, preserving the integrity of your vehicle’s original setup. All brackets are CNC machined and welded to exacting standards, guaranteeing durability and precise fitment. The inlet and outlet connections replicate OEM specifications, allowing seamless integration with existing OEM or aftermarket hoses. This ensures a straightforward upgrade path without compromising reliability.
