The CSF all-aluminum radiator for 2015–2018 BMW M2 (F87) and 2012–2016 M235i/M235ix is a plug-and-play upgrade for N55-powered BMWs. It uses a 2-row 42mm core with B‑Tube technology and multi-louvered fins to increase cooling efficiency for street and track use. CNC‑machined inlet/outlet and auxiliary connections match OE fittings, and the unit installs without modifications for a direct replacement.
