All-Aluminum 2-Row 42mm Radiator

The CSF All-Aluminum Racing Radiator is engineered to provide superior cooling efficiency for a range of BMW E36 chassis vehicles. This high-performance radiator utilizes CSF's proprietary "B-Tube" technology, which creates a stronger, more efficient tube shape than traditional "O" type tubes. This design increases the heat transfer surface area by approximately 15%, allowing for "dual liquid laminar flow" and improved cooling performance. The core construction features a 2-row, 42mm design with ultra-efficient multi-louvered fins that are precisely aligned to maximize airflow and heat dissipation. The radiator is constructed from military-grade aluminum (JIS 3003 spec minimum) for tubes, fins, header, plates, and side brackets. It also includes CNC-machined fittings and brackets for durability and a precise fit, along with a "Master Class" TIG welding for robust construction. A "Racing Style" Aluminum Drain Plug is also included. Each CSF radiator undergoes rigorous testing, including hydrostatic, vacuum decaying, and life cycle testing, ensuring it meets "drop-in fit" standards. The "Show-Stopper™" hand-polished mirror finish adds an aesthetic appeal. This radiator is specifically designed to fit various BMW 3 Series models from 1992-1999, including the 320i, 323i, 325i, 328i, and M3. Key specifications include a 42mm core thickness, "B-Tube" technology, and multi-louvered fins. The radiator is brazed in a CAB furnace and is ISO 9001/9002 certified. It is manufactured in Indonesia and features OE radial and deep drawn aluminum end tanks.
