The CSF 8355 is an individual auxiliary radiator for the listed N55 F87 M2 and B58 F-series BMW applications. Its two-row, 42mm B-Tube core uses 5mm fins, an integrated frame and a detachable guard.

The N55 M2 uses a single left-side auxiliary radiator. Other listed F-series vehicles may have two or no auxiliary radiators depending on specification, so the actual equipment and original part number must be checked before selecting quantity.
