With over five decades of expertise in radiator manufacturing, CSF stands as a leader in delivering high-quality cooling solutions. The CSF Mazda ND Miata High-Performance All-Aluminum Radiator is engineered to provide superior cooling performance, ensuring your ND Miata operates efficiently under both street and track conditions. This radiator is an essential upgrade for vehicles with high horsepower configurations or for motorsport applications demanding enhanced thermal management.
At the core of this radiator lies a 2-Row design incorporating CSF's exclusive B-Tube Technology. Unlike conventional oval "O" shaped tubes, CSF's innovative "B" shaped tubes are precisely formed and seam-brazed to create a stronger, lighter, and more efficient cooling structure. This unique design allows the use of thinner aluminum, enhancing heat dissipation while maintaining structural integrity superior to traditional welded tubes. The B-Tube configuration increases the heat transfer surface area by approximately 15% compared to standard 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 exchange.
Complementing the B-Tube core, the radiator features ultra-efficient multi-louvered fins meticulously aligned to maximize airflow through the core. Each fin's dimensions and orientation are carefully engineered and validated through rigorous wind-tunnel testing to ensure optimal heat rejection performance tailored specifically for the ND Miata application.
The CSF ND Miata radiator is designed as a true "Drop-in fit," allowing for straightforward installation without the need for modifications. All brackets are CNC machined and welded to meet stringent durability standards, ensuring a secure and precise fit. The inlet and outlet connections are crafted to match OEM specifications, enabling seamless integration with original hoses or aftermarket components. This compatibility extends to all attaching OEM parts, including quick connect hoses, AC condenser, mounting brackets, and fan shroud, preserving the vehicle’s factory configuration.
