    The CSF 8355 is a high-performance auxiliary radiator for the BMW F87 M2 (N55), F30 340i, F34 340i GT, F32/F33/F36 440i and 430i, and F22/F23 M240i. An auxiliary radiator adds cooling capacity to the engine cooling system, lowering temperatures and delaying heat soak during aggressive driving so the engine is less likely to enter limp mode. It uses a 2-row 42mm core with CSF's B-Tube Technology and 5mm multi-louvered fins, in 100 percent TIG-welded aluminum with a satin black finish, an integrated mounting frame, a detachable rock guard, and OEM-style quick-connect inlet and outlet. It is a drop-in fit. Most cars use two auxiliary radiators, but the F87 M2 (N55) uses only one, mounted on the left. It does not fit the M2 Competition, which uses the S55 auxiliary radiators.
