CSF 03-07 Infiniti G35 (Coupe/Sedan) High-Performance All-Aluminum Radiator

With over five decades of expertise in radiator manufacturing, CSF stands as a leader in delivering superior cooling solutions. The CSF 03-07 Infiniti G35 (Coupe/Sedan) High-Performance All-Aluminum Radiator exemplifies this legacy by combining advanced engineering with durable materials to ensure optimal engine temperature regulation. Whether your G35 is driven on the street or pushed to its limits on the track, this radiator is engineered to meet the demanding cooling requirements of both high-performance street vehicles and motorsports applications.

At the core of this radiator is a 2-Row 42mm core featuring CSF's exclusive B-Tube Technology. Unlike conventional oval "O" shaped tubes, CSF’s innovative "B" shaped tubes are precision-formed and seam-brazed, resulting in a stronger yet lighter structure. This design allows the use of thinner aluminum, enhancing heat dissipation efficiency without compromising durability. The unique B-Tube configuration increases the heat transfer surface area by approximately 15% compared to traditional tubes, effectively delivering the cooling capacity of two smaller tubes within the same spatial constraints. This advancement facilitates dual liquid laminar flow, optimizing coolant movement and heat rejection.

Complementing the B-Tube core, CSF integrates ultra-efficient multi-louvered fins meticulously aligned to maximize airflow through the radiator. Each fin is engineered with a 6.5mm height and a multi-louvered design, which significantly increases the surface area for heat exchange. These specifications are carefully calculated and validated through rigorous wind-tunnel testing to ensure maximum thermal performance under diverse operating conditions.

The radiator is designed as a true "drop-in fit" replacement, requiring no modifications during installation. All original equipment (OE) style brackets are CNC machined and welded to provide exceptional strength and longevity. The inlet and outlet connections are engineered to match OE specifications precisely, allowing seamless integration with existing OEM hoses or compatible aftermarket components. This ensures a hassle-free installation process while maintaining the integrity of the vehicle’s cooling system.
