CSF, the industry leader in high-performance BMW cooling, is the top choice for F3X and F2X owners who want more than just OEM reliability. Whether you're building a serious track machine or simply want a bulletproof upgrade, the new CSF High-Performance Radiator delivers unmatched durability and cooling efficiency for your Gen 1 B58 BMW.
CSF has built a reputation for producing the best B58 cooling systems on the market. Backed by years of experience and input from customers, race teams, and development partners, CSF leads the industry in Gen 1 B58 cooling technology.
As more enthusiasts push the performance limits of F-Chassis BMWs, the factory radiator has started to show its age. Increased boost and upgraded turbos generate significantly more heat, and the stock system can struggle to keep up. Combined with the heat exchanger mounted in front of the radiator, engine coolant temps can get too hot, especially during track use which can trigger limp mode.
On top of that, OEM plastic radiators degrade over time. With clogged tubes, damaged fins, and a higher risk of cracked tanks or gasket failure, replacing the stock radiator becomes essential for long-term reliability and performance.
Key Design Features: 20-25% increase in heat transfer efficiency using CSF's exclusive 5mm fin technology. Improved cooling performance to support high-boost, big-turbo builds. All-aluminum construction for superior durability over OEM plastic tanks. Designed to work seamlessly with factory or aftermarket heat exchangers.
Whether you're building a street sleeper or prepping for your next track day, CSF's Gen 1 B58 Radiator is engineered to handle the heat and then some.
