The OEM B58 heat exchanger is a 1-row, 27 mm thick. CSF has used the world's largest 2-row cell (68 mm) with CSF's B-Tube technology. Thanks to the unique design, the larger CSF cell still fits in the OEM space. Another critical feature of the CSF BMW B58 heat exchanger is its unique triple flow design. The water passing through the upgraded heat exchanger flows through the radiator three times before it leaves the radiator and flows back into the charge cooler. This ensures that the temperature of the heat exchanger's outlet water is as low as possible.

Available in black or silver color.
