An all-aluminum, 2-row radiator for the Audi B8 S4/S5 and other 3.0L/3.2L Audi models, built with CSF's B-Tube core for improved heat transfer. Drop-in fit with OE-style connections; automatic-transmission versions get an added plate-type transmission oil cooler in the left tank (pre-plugged for manual cars).
