CSF 98-05 Mazda NB Miata High-Performance All-Aluminum Radiator

With over five decades of dedicated expertise in radiator manufacturing, CSF stands as a leader in delivering superior cooling solutions. The CSF 98-05 Mazda NB Miata High-Performance All-Aluminum Radiator exemplifies this commitment, engineered to ensure optimal engine temperature management and reliable performance for your NB Miata. Whether for spirited street driving or demanding track environments, this radiator meets the rigorous cooling demands of high horsepower engines and motorsport applications alike.

At the core of this radiator lies a meticulously designed 2-Row core featuring CSF's exclusive B-Tube Technology. Unlike conventional oval "O" shaped radiator tubes, CSF employs a uniquely engineered "B" shaped tube. These tubes are precision-formed and seam-brazed, creating a robust structure that surpasses the strength of traditional welded "O" tubes. This innovative design allows the use of thinner, lighter aluminum material without compromising durability, while enhancing cooling efficiency.

The "B-Tube" design increases the heat transfer surface area by approximately 15% compared to standard tubes, effectively providing the cooling capacity equivalent to two smaller tubes within the same spatial constraints. This configuration facilitates dual liquid laminar flow, optimizing heat dissipation and maintaining consistent engine temperatures under high stress. Complementing this advanced tubing, the radiator incorporates ultra-efficient multi-louvered fins precisely aligned to maximize airflow through the core. Each fin is engineered with a 6.5mm height and a multi-louvered pattern, carefully calculated and validated in CSF’s wind-tunnel laboratory to ensure maximum heat rejection performance.

Installation is straightforward and user-friendly, as the CSF NB Miata radiator is designed as a true "Drop-in fit" replacement. It requires no modifications, preserving the integrity of your vehicle’s original setup. The OE-style brackets are CNC machined and welded to provide exceptional durability and precise fitment. Furthermore, the inlet and outlet connections are CNC machined to match OEM specifications, allowing seamless compatibility with original or aftermarket hoses.
