CSF Radiator for MK4 Supra 2-Row All-Aluminum Core with B-Tube Technology

CSF Radiator for MK4 Supra — 2-Row All-Aluminum Core with B-Tube Technology CSF brings over five decades of thermal engineering to the MK4 Supra. This high-performance, all-aluminum radiator is built for spirited street driving and demanding track use, delivering reliable cooling for high-horsepower builds and race vehicles. Key Features 2-row all-aluminum core optimized for weight savings and rapid heat rejection. B-Tube Technology — uniquely formed "B" shaped tubes brazed at the seam for greater strength and increased tube surface area (~15% more than conventional tubes), improving heat transfer without added bulk. Dual liquid laminar flow achieved by the B-tube design, simulating two smaller tubes in the same footprint for superior cooling efficiency. Multi-louvered fins precisely aligned and tuned per application to maximize airflow and heat rejection (validated in CSF wind-tunnel testing). Ideal for both street performance and motorsports environments where consistent engine temps matter. Benefits Lower operating temperatures under load, reducing risk of heat soak. Durable, lightweight construction improves vehicle response and longevity. Direct-fit design for MK4 Supra for straightforward installation. Upgrade your MK4 Supra cooling system with CSF’s advanced B-Tube radiator for dependable, race-proven performance and efficient heat management.
