Further Information
CSF brings over five decades of cooling expertise to the 04-08 Mazda RX-8 with this high-performance all-aluminum radiator. Engineered for both street and track use, this radiator delivers the added cooling performance needed for high horsepower builds and motorsports environments.
This 2-row 42mm core features CSF's exclusive B-Tube Technology, a specially engineered tube design that is stronger than conventional O-shaped tubes while using thinner, lighter aluminum. The seam-brazed design creates dual liquid laminar flow and increases heat transfer surface area by approximately 15% compared to standard tubes. Combined with ultra-efficient multi-louvered fins precisely aligned for maximum airflow, this radiator is optimized for maximum heat rejection.
