With over five decades of expertise in radiator manufacturing, CSF stands as a trusted leader in delivering high-quality cooling solutions. The CSF 02-06 Acura RSX High-Performance All-Aluminum Radiator exemplifies this legacy, engineered to provide superior cooling efficiency and reliability for your Acura RSX. Whether you are driving on the street or pushing the limits on the track, this radiator ensures optimal engine temperature management, which is critical for maintaining performance and longevity in both daily and high-demand motorsport environments.
This radiator is designed with a 2-Row 42mm core that incorporates CSF’s exclusive B-Tube Technology. Unlike conventional oval “O” shaped tubes, the innovative “B” shaped tubes are precision-formed and seam-brazed to create a stronger, lighter structure. This advanced design allows the use of thinner aluminum material without compromising durability, enhancing heat transfer efficiency by approximately 15% compared to traditional tubes. The increased surface area facilitates dual liquid laminar flow, which significantly improves cooling capacity within the same spatial constraints.
Complementing the B-Tube core, the radiator features ultra-efficient multi-louvered fins with a 6.5mm fin height. These fins are meticulously aligned and engineered to maximize airflow through the core, optimizing heat rejection. Each fin specification is carefully calculated and validated through rigorous wind-tunnel testing to ensure peak thermal performance under various operating conditions.
Installation of the CSF RSX radiator is straightforward due to its true "Drop-in fit" design. This eliminates the need for any modifications, allowing for seamless replacement of the original radiator. The radiator includes CNC-machined brackets and fittings that guarantee precise fitment and enhanced durability. Additionally, the inlet and outlet connections are CNC machined to match original equipment specifications, enabling compatibility with OEM hoses and aftermarket components alike.
