CSF 2863 Radiator for MAZDA Miata 1998-2005

Part number2863

With over fifty years of experience in radiator manufacturing, CSF is the obvious choice when it comes to keeping your Mazda NB Miata's engine cool and performing at its peak. Designed for track or race applications, this high-performance, all-aluminum radiator is a must-have for both high-performance street cars and race cars that require enhanced cooling efficiency in motorsport environments. This radiator features a 2-row core with CSF's exclusive B-Tube Technology: Unlike conventional "O" shaped radiator tubes, CSF uses specially designed "B" shaped tubes. These B-tubes are carefully formed and then seam-soldered to seal them. CSF can use thinner, lighter aluminum material (with greater cooling efficiency) because this design is actually stronger than conventional "O" tube welded tubes. The design (inlet opening in the middle of the tube, seam-soldered) increases the surface area of the tubes' heat exchange by approximately 15% compared to conventional tubes – the efficiency of two smaller tubes compared to one larger tube under the same space criteria. With B-tubes, "dual-row laminar flow" can be achieved. CSF also utilizes highly efficient fin stocks that are carefully and precisely aligned to maximize airflow through the radiator core. Fin specs are carefully measured and calculated for each application and tested in a wind tunnel for maximum heat dissipation efficiency.

The CSF Radiator for the Mazda NB Miata is a true "Drop-in fit" design, requiring no modifications for installation. The OE-style mounting brackets are CNC-machined and welded for maximum strength. The inlet/outlet fittings are designed to match the OEM fittings, so you can use OEM or aftermarket hoses. Trust the cooling experts at CSF for the most efficient, high-quality, and reliable radiators.
