CSF 2862 Radiator for MAZDA Miata 1989-1997

Part number2862

With over fifty years of experience in radiator manufacturing, CSF is the obvious choice when it comes to keeping your Mazda NA Miata's engine cool and performing at its peak. Engineered for both street and track use, this radiator is a must-have for high-performance builds and race cars requiring enhanced cooling efficiency in motorsport conditions. This radiator features a 2-row core with CSF's exclusive "B-Tube" technology: Unlike standard "O" style oval radiator tubes, CSF utilizes specially designed "B-Tube" shaped tubes. These B-tubes are meticulously 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 standard "O" style 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 standard tubes – the efficiency of two smaller tubes versus one larger tube under the same space constraints. With B-tubes, "dual-row laminar flow" can be achieved. CSF also utilizes highly efficient louvered fins that are precisely and accurately aligned to maximize airflow through the radiator core. Fin characteristics are carefully measured and calculated for each application, and tested for maximum heat dissipation efficiency in a wind tunnel laboratory.

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