CSF 7059 Aluminum Radiator for BMW M3 E90/E92

Part number7059

With over fifty years of experience in radiator manufacturing, CSF is the obvious choice when it comes to keeping your BMW E9X M3's engine cool and performing at its peak. Designed for track or race use, this high-performance, all-aluminum radiator is a must-have for both high-performance street cars and race cars that require additional cooling efficiency in motorsport conditions. The triple-pass flow structure allows coolant to pass through the radiator core three times before exiting, ensuring minimal outlet temperatures. This radiator features a 2-row core with CSF's exclusive "B-Tube" technology: Unlike conventional "O" style oval radiator tubes, CSF uses specially designed "B" shaped tubes. These B-tubes are carefully formed and then brazed along the seam to seal. CSF can use thinner and lighter aluminum material (with greater cooling efficiency) because this design is actually stronger than conventional "O" style welded tubes. The design (inlet opening in the middle of the tube, brazed along the seam) increases the surface area of the tubes' heat exchange by approximately 15% compared to conventional tubes – the efficiency of two smaller tubes compared to one larger tube within the same space criteria. With B-tubes, "dual-core laminar flow" can be achieved. CSF also utilizes highly efficient fin stocks that are carefully and precisely aligned to maximize airflow through the radiator core. Fin specs are carefully measured and calculated for each application and tested in a wind tunnel for maximum heat dissipation efficiency.

The CSF radiator for the BMW E9X M3 is a true "drop-in fit" design, requiring no modifications for installation. OE-style mounting brackets are CNC-machined and welded for maximum strength. The inlet/outlet ports are designed to match the original ports, so you can use OEM or aftermarket hoses.
