CSF High Performance Radiator - BMW E28 M5 | E24 M6 | M635CSi

The original E28 M5 and E24 M6 radiators use an aluminium core with plastic tanks – typical of the era, but cooling technology has moved on a long way since. CSF's High Performance Radiator brings these classic M cars up to date with an all-aluminium, TIG-welded design and a 1-row 31mm core using CSF's B-Tube technology.

With nearly double the number of tubes and fins of the OEM unit and super-efficient multi-louvred fins, it comfortably outperforms the original. It mounts in the factory location with no cutting or modification, and the satin black finish keeps an OEM+ look under the bonnet.
