CSF Aluminum Radiator for F2X/F3X with 2-Row Core and B-Tube Technology

CSF Aluminum Radiator for F2X/F3X — 2-Row Core with B-Tube Technology Upgrade engine cooling for your F2X/F3X with CSF’s high-performance all-aluminum radiator. Backed by over five decades of radiator engineering, this unit is built for street use and track demands, offering reliable temperature control for high-horsepower builds and race vehicles. Key Features 2-Row Core — Optimized core layout for increased heat rejection in compact applications. B-Tube Technology — Specially formed, seam-brazed "B" shaped tubes provide ~15% more heat transfer surface area versus conventional oval tubes. Dual Liquid Laminar Flow — B-tubes emulate the efficiency of two smaller tubes in the same space for improved coolant dynamics. Ultra-Efficient Multi-Louvered Fins — Precisely aligned fins maximize airflow and thermal exchange; fin geometry tuned per application and validated in CSF’s wind-tunnel lab. Lightweight, Durable Construction — Thinner, stronger aluminum material enabled by brazed B-tube design for weight savings without sacrificing strength. Benefits Lower operating temperatures under high load Improved reliability for performance and motorsport use Optimized fit and airflow for F2X/F3X platforms Tested design for consistent, repeatable cooling efficiency Choose CSF for proven cooling innovation — engineered to keep your engine running cooler, longer, and harder.
