CSF 7081 High Performance Radiator for BMW M235i (F23) / 435i (F36)

With over fifty years of experience in radiator manufacturing, CSF is the obvious choice when it comes to keeping your BMW F2X/F3X engine cool and performing at its best. Designed for track-day use or spirited driving, this high-performance, all-aluminum radiator is a must-have for both high-performance models and race cars that require enhanced cooling efficiency in motorsport applications. This radiator features a 2-row core with CSF's exclusive B-Tube Technology: Unlike conventional "O" type oval radiator tubes, CSF utilizes specially engineered "B" shape tubes. These B-tubes are carefully formed and then seam-soldered to seal them. CSF can use a thinner, lighter aluminum material (with greater cooling efficiency) because this design is actually stronger than conventional "O" shape welded tubes. The design (inlet opening in the middle of the tube, seam-soldered) increases the heat exchange surface area of the tubes by approximately 15% compared to standard tubes – the efficiency of two smaller tubes versus one larger tube within the same space criteria. With B-tubes, a "dual-row laminar flow" can be achieved. CSF also utilizes ultra-efficient fin stocks that are carefully and precisely aligned to maximize airflow through the radiator core. The fin characteristics are carefully measured and calculated for each application and tested for maximum heat dissipation efficiency in a wind tunnel laboratory.

The CSF Radiator for BMW F2X/F3X is a true "Drop-in fit" design, requiring no modifications for installation. All OE-style mounting brackets are CNC-machined and welded for maximum strength. The inlet/outlet connections are designed to match original connections, so you can use stock or aftermarket hoses. Trust the cooling experts at CSF for the most efficient, high-quality, and reliable radiators.
