If you’re looking to modify, upgrade, or simply keep up with the maintenance on an Audi B5 S4, upgrading the cooling system with CSF’s high-performance all-aluminum radiator is highly recommended. It’s another crucial fix along with a laundry list of other items to replace and maintain on the iconic B5 S4. Keep in mind that these cars are 15-20 years old, and if you haven’t already replaced your original plastic tank radiator, the time is definitely coming soon! Until now, there has not been a reliable, drop-in fit option with an acceptable price point offered in the market but CSF has answered the call!
