CSF Radiator for 1997 - 2002 Audi S4 (B5)

An all-aluminum replacement radiator for the Audi B5 S4, whose original plastic-tank radiators are prone to failing as the cars pass 20+ years old. Useful when adding a tune or bolt-on boost upgrades to the 2.7L twin-turbo V6, since extra power increases cooling demand.
