CSF 7001 Radiator for BMW E90 325i/328i N52 3.0L

Part number7001

With over fifty years of experience in radiator manufacturing, CSF is the obvious choice when it comes to ensuring optimal engine cooling and performance for your BMW E9X/E8X. Designed for track or street use, this high-performance, all-aluminum CSF radiator is a must-have for both high-performance street cars 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 standard "O" type oval radiator tubes, CSF utilizes specially engineered "B-shaped" tubes. These B-tubes are meticulously formed and then seam-soldered to seal them. CSF can use thinner, lighter aluminum material (with greater cooling efficiency) because this design is actually stronger than standard welded "O" shaped tubes. The design (inlet opening in the middle of the tube, seam-soldered) increases the surface area of the tubes' heat exchange by approximately 15% compared to standard tubes – the efficiency of two smaller tubes versus one larger tube within the same space criteria. With the B-tubes, a "dual-core laminar flow" can be achieved. CSF also utilizes highly efficient fin stock that is carefully and precisely aligned to maximize airflow through the radiator core. The fin characteristics are meticulously measured and calculated for each application, and tested for maximum heat dissipation efficiency in a wind tunnel laboratory.

The CSF Radiator for the BMW E9X/E8X 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 ports are designed to match the OEM specifications, allowing you to use stock or aftermarket hoses. Trust the cooling experts at CSF for the most efficient, high-quality, and reliable radiators.
