CSF 03-06 Nissan 350Z (DE Engine) High-Performance All-Aluminum Radiator

With over five decades of expertise in radiator manufacturing, CSF stands as a leader in delivering high-quality cooling solutions for automotive applications. The CSF 03-06 Nissan 350Z (DE Engine) High-Performance All-Aluminum Radiator exemplifies this commitment, engineered to provide superior cooling performance for both street and track use. This radiator is an essential upgrade for high horsepower builds and race vehicles that demand enhanced thermal management in demanding motorsports environments.

At the core of this radiator's exceptional performance is CSF's proprietary B-Tube Technology integrated into a 2-Row 42mm core. Unlike conventional oval-shaped "O" tubes, CSF's innovative "B" shaped tubes are precision-formed and seam-brazed to create a stronger, lighter, and more efficient structure. This design allows the use of thinner aluminum material without sacrificing durability, resulting in improved heat transfer capabilities. The unique "B-tube" configuration increases the heat transfer surface area by approximately 15% compared to standard tubes, effectively delivering the cooling efficiency of two smaller tubes within the same spatial constraints. Moreover, the design facilitates dual liquid laminar flow, optimizing coolant movement for enhanced thermal dissipation.

Complementing the advanced core technology, the radiator employs ultra-efficient multi-louvered fins with a 6.5mm fin height, meticulously aligned to maximize airflow through the core. Each fin specification is carefully calculated and validated through rigorous wind-tunnel testing to ensure maximum heat rejection efficiency, thereby maintaining optimal engine temperatures under strenuous conditions.

The CSF 350Z radiator features a true "drop-in fit" design, enabling straightforward installation without any modifications. All OE-style brackets are CNC machined and welded, ensuring superior durability and precise fitment. The inlet and outlet connections are engineered to match original equipment specifications, allowing seamless reuse of OEM hoses or compatible aftermarket alternatives. This attention to detail guarantees compatibility with all attaching components, including quick-connect hoses, AC condenser, mounting brackets, and fan shroud, preserving the integrity of the vehicle’s cooling system.
