Upgrade your cooling system with the ultimate track-ready solution. The CSF 7226 High-Performance All-Aluminum Radiator delivers unparalleled thermal efficiency for the Toyota GR Supra and BMW G-Series platforms. Engineered to eliminate heat soak and survive extreme pressure, this true drop-in upgrade replaces weak factory plastic tanks with heavy-duty, TIG-welded aluminum.
- Maximum Heat Transfer: Dual-row 42mm ultra-performance core maximizes surface area for aggressive cooling.
- Exclusive B-Tube Technology: Specially engineered tubes increase heat dissipation by 15% over standard oval designs.
- Track-Spec Fin Design: 5mm multi-louvered fins optimize airflow and reject heat under severe driving conditions.
- 100% TIG-Welded Aluminum: Eliminates the common failure point of brittle, leaking OEM plastic end tanks.
- True Drop-In Fitment: CNC-machined brackets and quick-connect fittings allow easy installation with no cutting required.
Don't let heat soak hold your performance back. Whether you are attacking the track, pushing high horsepower on a tuned street car, or building a heavy forced-induction monster, factory cooling systems quickly reach their limit. The CSF 7226 All-Aluminum Radiator is built to handle the extreme demands of high-performance driving.
At the heart of this radiator is CSF’s proprietary B-Tube technology. Unlike standard welded oval tubes, B-Tubes are rolled and reinforced, creating a dual-channel flow path that enhances heat transfer surface area by 15%. Paired with a massive 42mm dual-row core and ultra-efficient 5mm multi-louvered fins, this radiator drops operating temperatures and keeps your engine running at peak efficiency longer.
Built for both reliability and aesthetics, the CSF 7226 features hand-crafted, TIG-welded end tanks that easily withstand high cooling system pressures. The entire unit receives a 1-hour hand polish for a breathtaking mirror finish. Designed as a true plug-and-play upgrade, it utilizes all factory mounting points, fan shrouds, and OEM quick-connect coolant hoses for a seamless, modification-free installation.
