CSF High Performance Aluminum Radiator - 2013+ Scion FR-S / Toyota 86 / 22+ Subaru BRZ / GR86

When it comes to keeping your engine cool under pressure, few brands match the pedigree of CSF. With over five decades of manufacturing experience, CSF’s High-Performance All-Aluminum Radiator is the ultimate cooling upgrade for the Scion FR-S, Subaru BRZ, Toyota 86, and GR86. Whether you’re carving canyons, daily driving, or chasing lap times, this radiator delivers superior cooling capacity and reliability.

Built for high horsepower street cars and demanding motorsport environments, this CSF radiator features a 2-row 42mm dual-core design utilizing CSF’s proprietary B-Tube Technology. Unlike standard “O” shaped tubes, CSF’s precision-engineered “B” tubes are stronger and lighter, allowing thinner aluminum walls for improved heat transfer. This design increases internal surface area by up to 15%, promoting dual laminar liquid flow for maximum thermal efficiency.

Complementing the B-Tube design is CSF’s multi-louvered fin structure, optimized through wind-tunnel testing for maximum airflow and heat rejection. Every fin height, spacing, and angle is precision-calculated to ensure consistent, high-efficiency cooling under the toughest conditions.
