CSF 13-20 FR-S / BRZ / 86 / 22+ GR86 / BRZ High-Performance All-Aluminum Radiator

With over five decades of expertise in radiator manufacturing, CSF stands as a benchmark for quality and reliability in automotive cooling solutions. The CSF 13-20 FR-S / BRZ / 86 / 22+ GR86 / BRZ High-Performance All-Aluminum Radiator exemplifies this legacy, engineered to maintain optimal engine temperatures for your vehicle, whether on the street or the racetrack. This radiator is meticulously designed to meet the rigorous demands of high horsepower applications and motorsport environments, where enhanced cooling efficiency is critical for performance and durability.

At the core of this radiator is CSF’s innovative 2-Row core featuring exclusive B-Tube Technology. Unlike conventional oval-shaped “O” tubes, the B-Tube design is a specially engineered structure shaped like the letter “B.” These tubes are precision-formed and seam-brazed to ensure a robust seal, allowing the use of thinner, lighter aluminum material without compromising strength. This advanced design increases the heat transfer surface area by approximately 15% compared to traditional tubes, effectively delivering the cooling efficiency of two smaller tubes within the same spatial constraints. The result is a superior dual liquid laminar flow that maximizes heat dissipation.

Complementing the B-Tube technology, the radiator incorporates ultra-efficient multi-louvered fins with a 6.5mm fin height. These fins are carefully aligned to optimize airflow through the core, enhancing heat rejection capabilities. Each fin specification is precisely calculated and validated through rigorous wind-tunnel testing to ensure maximum thermal performance under demanding conditions.

The CSF radiator is engineered as a true “drop-in fit” component, requiring no modifications for installation. All brackets are CNC machined and welded to exacting standards, ensuring exceptional durability and a perfect fit. The inlet and outlet connections are designed to mirror OEM specifications, enabling seamless integration with original or aftermarket hoses. This design philosophy guarantees compatibility with all factory components, including quick-connect hoses, AC condensers, mounting brackets, and fan shrouds.
