The CSF 7232 is a high-performance all-aluminum radiator for the BMW E28 M5, in both US and Euro form, and the E24 M6 and M635CSi, all running the S38 or M88 3.5L inline-six. It also covers the E24 635CSi. It uses a 1-row 31mm ultra-high-performance core with 47 cooling tubes on CSF's B-Tube design for about 15 percent more heat-transfer surface than a regular tube, and 6.5mm multi-louvered fins across 48 fin rows. It is TIG-welded all-aluminum with aluminum tanks in place of the OEM plastic units, and is a true drop-in fit that uses OEM-style mounting brackets and the original hoses.
