CSF 00-09 Honda AP1/AP2 S2000 High-Performance All-Aluminum Radiator

With over five decades of expertise in radiator manufacturing, CSF stands as a leader in delivering high-performance cooling solutions. The CSF 00-09 Honda AP1/AP2 S2000 High-Performance All-Aluminum Radiator embodies this legacy, engineered to maintain optimal engine temperatures and ensure your S2000 operates at peak efficiency under all conditions. Whether for spirited street driving or demanding track use, this radiator is an essential upgrade for vehicles with high horsepower configurations or those engaged in motorsports, where enhanced cooling capacity is critical.

At the core of this radiator is a 2-Row 42mm design featuring CSF’s proprietary B-Tube Technology. Unlike conventional oval "O" shaped tubes, CSF’s innovative "B" shaped tubes are meticulously formed and seam-brazed to create a robust structure. This advanced design allows the use of thinner, lighter aluminum material without compromising strength, resulting in superior cooling efficiency. The unique inlet positioned centrally within the tube and the seam brazing increase the heat transfer surface area by approximately 15% compared to traditional tubes. This enhancement effectively doubles the cooling performance within the same spatial constraints by enabling dual liquid laminar flow through the tubes.

Complementing the B-Tube core, the radiator incorporates ultra-efficient multi-louvered fins, precisely aligned to maximize airflow through each core. These fins, with a fin height of 6.5mm, are engineered to optimize surface area contact, thereby significantly improving heat rejection. Each fin configuration is carefully calculated and rigorously tested in CSF’s wind tunnel laboratory to ensure maximum thermal performance tailored to the S2000 application.

The CSF S2000 radiator is designed as a true "drop-in fit" replacement, requiring no modifications during installation. It features CNC-machined and welded OE-style brackets for exceptional durability and precise fitment. The inlet and outlet connections are CNC-machined to match original equipment specifications, allowing seamless integration with OEM hoses or aftermarket components. This ensures compatibility with all factory attachments, including quick-connect hoses, the AC condenser, mounting brackets, and fan shroud, facilitating a straightforward and reliable installation process.
