High-Performance 2-Row 42mm Heat Exchanger

The CSF High-Performance Heat Exchanger (model #8154) is engineered to solve the common overheating and heat soak issues experienced by the 2nd gen B58 Motor's liquid-cooled charge air cooler system. This problem can lead to significant intake air temperature (IAT) spikes, causing the ECU to cut power and potentially engage limp mode, especially during spirited driving or with performance modifications. This upgraded unit utilizes a significantly larger 2-row, 42mm ultra-high-performance core, enhanced with CSF's exclusive B-Tube technology. In comparison to the stock 1-row, 25mm heat exchanger, this CSF core provides superior cooling. The design also incorporates unique tank engineering to accommodate the larger core within the OEM cooling system housing. Features include CNC machined mounting brackets, OEM-style quick connect inlet/outlets, and 100% TIG-welded aluminum construction for durability. CSF has further enhanced this heat exchanger with a durable metal rock guard and integrated billet transmission cooler mounts. This makes it a true plug-and-play, "drop-in" fit. The core also features "Track-Spec" 5mm tall ultra-efficient fins with a multi-louvered design, maximizing surface area for heat dissipation. This component is crucial for maintaining optimal charge air temperatures, especially when upgrading turbos or running performance tuning software. It also helps improve airflow to the rest of the cooling system, leading to lower engine coolant and oil temperatures. The unit comes with a 2-year limited warranty and a smooth satin finish. It has been tested and proven by CSF's global network of R&D partners, including leading time attack teams, tuners, and turbo kit manufacturers.
