Description

The CSF 8355 High-Performance Auxiliary Radiator is designed for BMW F87 M2 (N55 engine) and Gen-1 B58 models, including the F3x 340i / 440i, and F2x M240i / M140i. This radiator is a direct drop-in fit and is sold individually, with most applications using two auxiliary radiators. It features a 2-row, 42mm high-performance core with CSF's exclusive B-tube technology and 5mm tall ultra-efficient fins for maximum heat dissipation. The construction is 100% all-aluminum, TIG-welded, and includes an integrated mounting frame with bolt-on rock guards for increased durability. The finish is satin black for an OEM+ look.
