CSF Porsche 996 Carrera / GT3 / GT3 RS / 986 Boxster (Center) All-Aluminum Radiator

With over five decades of expertise in radiator manufacturing, CSF stands as a leading authority in delivering high-quality cooling solutions. The CSF Porsche 996 Carrera / GT3 / GT3 RS / 986 Boxster (Center) All-Aluminum Radiator exemplifies this legacy, engineered to maintain optimal engine temperatures and ensure peak performance for your Porsche 996 911 or 986 Boxster. Whether for street use or demanding track conditions, this radiator is an essential upgrade for vehicles requiring enhanced cooling capacity, particularly those with high horsepower or engaged in motorsports.

This radiator incorporates a 2-Row, 42mm core featuring CSF's proprietary B-Tube Technology. Unlike conventional oval-shaped "O" tubes, CSF's innovative "B" shaped tubes are meticulously formed and seam-brazed to create a stronger, lighter, and more efficient cooling element. This design allows for the use of thinner aluminum material, which improves heat dissipation while maintaining structural integrity superior to traditional welded tubes. The unique inlet positioned centrally within the tube increases the heat transfer surface area by approximately 15%, effectively delivering the cooling efficiency equivalent to two smaller tubes within the same spatial constraints. This configuration facilitates dual liquid laminar flow, optimizing coolant movement and thermal exchange.

Complementing the B-Tube core are ultra-efficient multi-louvered fins, precisely aligned to maximize airflow across the radiator surface. Each fin’s dimensions and placement are carefully engineered and validated through rigorous wind-tunnel testing to ensure maximum heat rejection capacity. This meticulous attention to detail guarantees superior cooling performance under a variety of operating conditions.

The CSF radiator is designed as a true "drop-in fit" replacement, requiring no modifications for installation. All original equipment (OE) style brackets are CNC machined and welded to ensure exceptional durability and precise fitment. The inlet and outlet connections mirror OE specifications, allowing seamless integration with existing OEM hoses or compatible aftermarket components. This ensures a straightforward installation process while maintaining the reliability and performance standards expected by Porsche enthusiasts and professionals alike.
