CSF Porsche 996 911 / 986 Boxster (Fits Left/Right) All-Aluminum Radiator

With over five decades of expertise in radiator manufacturing, CSF stands as a leader in delivering superior cooling solutions tailored for the Porsche 996 911 and 986 Boxster models. The CSF High-Performance All-Aluminum Radiator is engineered to maintain optimal engine temperatures, ensuring your vehicle operates at peak performance whether on the street or the racetrack. This radiator is indispensable for high horsepower applications and motorsport environments where enhanced cooling capacity is critical.

At the core of this radiator lies a 2-Row design incorporating CSF’s proprietary B-Tube Technology. Unlike conventional oval-shaped "O" tubes, CSF’s B-Tubes are uniquely shaped and seam-brazed to create a robust, leak-resistant structure. This innovative design allows the use of thinner, lighter aluminum material without compromising strength, delivering superior heat dissipation. The B-Tube’s central inlet and brazed seam increase the heat transfer surface area by approximately 15% compared to traditional tubes, effectively doubling the cooling efficiency within the same spatial constraints. This results in a dual liquid laminar flow that significantly enhances thermal exchange.

Complementing the B-Tube core, CSF employs ultra-efficient multi-louvered fins meticulously aligned to maximize airflow through the radiator. Each fin is precisely engineered and validated through rigorous wind-tunnel testing to ensure optimal heat rejection performance. This meticulous attention to detail guarantees that the radiator not only meets but exceeds OEM cooling standards.

The CSF radiator is designed as a true "drop-in fit," requiring no modifications for installation. All mounting brackets are CNC machined and welded to provide exceptional durability and exact fitment. The inlet and outlet connections mirror OEM specifications, allowing seamless integration with existing OEM hoses or aftermarket alternatives. This ensures a hassle-free upgrade while preserving the integrity of your vehicle’s cooling system.
