8131 ; BMW F3X/F2X B58/B48 Triple-Pass Heat Exchanger w/ Rock Guard - Silver

As the 3.0 Liter B58B30M0 (1st gen B58) turbo engine platform continues to be developed by the high performance industry and more power is extracted from the engine, CSF's high performance heat exchanger for the BMW B58 engine will be a critical component to keeping the vehicle charge air cool, and out of limp mode. The CSF BMW B58 upgraded heat exchanger for F-series vehicles will be especially important to install in upgraded turbo applications and/or vehicles running high performance tuning software.; The CSF #8131 comes in a Polished Finish. It is also available in a Satin Black Finish for OEM+ look (CSF #8131B).; The original OEM B58 heat exchanger is a 1-row unit that is 27mm thick. In comparison, CSF has used its industry-exclusive world's largest 2-row core (68mm) with CSF's B-Tube technology. A unique tank design allows the larger CSF core to still fit into the OEM cooling system housing. Another critical feature of the CSF BMW B58 high-performance heat exchanger is its unique triple-pass flow design. The water traveling through the upgraded heat exchanger flows through the radiator three times before exiting the cooler and flowing back into the manifold charge cooler. This ensures that the outlet water temperature of the heat exchanger is the absolute lowest it can be. The OEM design, as well as more expensive aftermarket designs, all have single-pass flow structures.
