CSF 3164 Radiator for MAZDA RX-8 2004-2008

Part number3164

With over fifty years of experience in radiator manufacturing, CSF is the obvious choice when it comes to keeping your Mazda RX-8's engine cool and performing at its peak. Designed for track-day or track use, 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 conditions. This radiator features a 2-row core with CSF's exclusive "B-Tube" technology: Unlike conventional "O" style oval radiator tubes, CSF uses specially designed "B-Tube" tubes. These B-tubes are meticulously formed and then seam-soldered to seal them. CSF can use a thinner, lighter aluminum material (with greater cooling efficiency) because this design is actually stronger than conventional "O" style welded tubes. The design (inlet opening in the middle of the tube, seam-soldered) increases the heat exchange surface area of the tubes by approximately 15% compared to conventional tubes – the efficiency of two smaller tubes compared to one larger tube within the same space criteria. With B-tubes, "double laminar flow" can be achieved. CSF also utilizes highly efficient fin stocks that are meticulously and precisely 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 RX-8 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 the original fittings, allowing you to use OEM or aftermarket hoses. Trust the cooling experts at CSF for the most efficient, high-quality, and reliable radiators.
