High-Performance Heat Exchanger 2-Row 42mm Core

The CSF High-performance heat exchanger is engineered to combat heat soak in the B58 motor's liquid-cooled charge air cooler system, a common issue that causes intake air temperatures (IATs) to spike, leading to ECU-induced power loss and limp mode. This upgraded heat exchanger utilizes an industry-exclusive 2-row core, measuring 42mm thick, featuring CSF's B-Tube technology. The "Track-Spec" design incorporates 5mm tall ultra-efficient fins with a multi-louvered pattern to maximize surface area contact and heat dissipation. Construction is 100% all-aluminum and TIG-welded for durability. It offers improved airflow to the rest of the cooling system, potentially lowering engine coolant and oil temperatures. CSF is unique in including a billet transmission cooler mount and a metal rock guard for improved airflow. This unit is tested and proven by CSF's global network of R&D partners, including time attack teams and tuners. The CSF #8154 heat exchanger is compatible with a wide range of BMW G-Series models (330i, M340i, 430i, M440i, Z4) from 2019-2026 and Toyota A90/A91 GR Supra models from 2020-2026, including various trims and engine sizes (2.0L L4, 3.0L L6). It comes with a 2-Year Limited Warranty.
