CSF Porsche 997 911 Turbo (Center) High-Performance All-Aluminum Radiator

With over five decades of expertise in radiator manufacturing, CSF stands as a trusted leader in delivering high-performance cooling solutions. The CSF Porsche 997 911 Turbo (Center) High-Performance All-Aluminum Radiator embodies this legacy, engineered to maintain optimal engine temperatures and ensure your 911 Turbo operates at peak efficiency under all conditions. Whether on the street or the racetrack, this radiator is an essential upgrade for vehicles demanding superior cooling capacity, particularly those with high horsepower or engaged in motorsport activities.

At the core of this radiator lies a 2-Row 42mm design incorporating CSF’s proprietary B-Tube Technology. Unlike conventional oval-shaped “O” type tubes, CSF’s B-Tubes feature a unique “B” shaped profile, meticulously formed and seam-brazed to enhance strength and durability. This innovative construction allows the use of thinner, lighter aluminum material without compromising structural integrity, resulting in improved cooling efficiency. The B-Tube design increases the heat transfer surface area by approximately 15% compared to traditional tubes, effectively delivering the cooling performance equivalent to two smaller tubes within the same spatial constraints. This dual liquid laminar flow capability significantly enhances heat dissipation, critical for high-performance engines.

Complementing the advanced tubing, the radiator employs ultra-efficient multi-louvered fins. These fins are precisely aligned and engineered to maximize airflow through the core, optimizing heat rejection. Each fin specification is carefully calculated and rigorously tested in CSF’s wind-tunnel laboratory to ensure maximum thermal efficiency. This attention to detail guarantees that the radiator performs reliably under demanding conditions, providing consistent cooling even during extended high-load operation.

Installation of the CSF 911 Turbo radiator is straightforward, featuring a true “drop-in fit” design that requires no modifications. The radiator includes CNC-machined and welded OE-style brackets, ensuring exceptional durability and precise fitment. Inlet and outlet connections are machined to match original equipment specifications, allowing seamless integration with OEM or aftermarket hoses. This compatibility simplifies installation and preserves the integrity of the vehicle’s cooling system.
