CSF 08-13 Nissan 370Z / 08-13 Infiniti G37 (AT) All-Aluminum Radiator

With over five decades of expertise in radiator manufacturing, CSF stands as a leader in delivering superior cooling solutions for high-performance vehicles. The CSF 08-13 Nissan 370Z / 08-13 Infiniti G37 (AT) All-Aluminum Radiator exemplifies this commitment, offering a precision-engineered cooling component designed to maintain optimal engine temperatures under demanding conditions. Whether for spirited street driving or competitive track use, this radiator provides the enhanced cooling capacity essential for high horsepower engines and motorsports applications.

At the core of this radiator’s innovation is CSF’s exclusive B-Tube Technology. Unlike conventional oval-shaped “O” type radiator tubes, the B-Tube design features a uniquely engineered “B” shaped tube that is seam-brazed for superior strength and durability. This construction allows the use of thinner, lighter aluminum material while simultaneously improving cooling efficiency. The B-Tube increases the heat transfer surface area by approximately 15% compared to traditional tubes, effectively delivering the cooling performance of two smaller tubes within the same spatial constraints. This design promotes dual liquid laminar flow, optimizing coolant movement and heat dissipation.

Complementing the advanced tube design, the radiator incorporates ultra-efficient multi-louvered fins with a 6.5mm fin height. These fins are meticulously aligned to maximize airflow through the 2-row, 42mm core, enhancing heat rejection capabilities. Each fin specification is precisely calculated and validated through rigorous wind tunnel testing to ensure maximum thermal performance tailored to the Nissan 370Z and Infiniti G37 applications.

The CSF radiator is engineered for a true “drop-in fit,” requiring no modifications during installation. All original equipment (OE) style brackets are CNC machined and welded to guarantee exceptional durability and precise fitment. The inlet and outlet connections are CNC machined to match OE specifications, allowing seamless integration with OEM hoses or aftermarket components. This attention to detail ensures compatibility with all factory attachments, including quick-connect hoses, AC condensers, mounting brackets, and fan shrouds, facilitating a hassle-free upgrade.
