The CSF 7078 is an aluminum engine coolant radiator for the listed N55 BMW M2, M235i and M Sport 335i/435i applications. A two-row, 42mm B-Tube core uses 6.5mm multi-louvered fins.
The radiator follows the original mounting and auxiliary-hose connection arrangement. On F3X cars, the documented M Sport equipment requirement is part of fitment; the engine or model badge alone is not enough to choose the correct radiator.

Does F87 fitment include the M2 Competition?
This listing covers the N55 M2. The S55 M2 Competition uses different cooling components.
