CSF B58 High-Performance Heat Exchanger: Unmatched Cooling Excellence

Introducing the CSF B58 High-Performance Heat Exchanger, the ultimate upgrade for your BMW B58 engine. This state-of-the-art heat exchanger is designed to deliver unparalleled cooling efficiency, ensuring your engine operates at peak performance. With its advanced features and robust construction, this heat exchanger is a must-have for any BMW enthusiast looking to enhance their vehicle's cooling system.

Next-Generation Design and Specifications

The CSF B58 Heat Exchanger has been upgraded to Version 2.0, featuring a new inlet/outlet design and core specifications that optimize cooling performance. Key improvements include a tapered entry and exit for optimized water flow, a 42mm 2-row core with CSF's B-tube technology, and a 6.5mm multi-louvered fin height for increased surface area contact and heat dissipation. The core is also 15% larger than the previous version, resulting in a 62% increase in fluid capacity for superior cooling efficiency. Additionally, the hardware mounting kit included with the product is specifically designed for applications with a factory transmission oil cooler, ensuring a seamless installation process.

Superior Performance and Everyday Benefits

The CSF B58 Heat Exchanger is not just a technical marvel; it offers practical benefits for everyday use. By lowering intake air temperatures (IATs), this heat exchanger maximizes the performance of your cooling system, especially in X-Drive models with transmission oil coolers. The triple-pass flow design and detachable rock guard further enhance cooling efficiency and protect the heat exchanger from road debris. With its direct plug-and-play installation and OEM CNC machined mounting location pins and brackets, this heat exchanger is the perfect choice for those seeking to upgrade their BMW's cooling system without the need for modifications. Whether you're a daily driver or a high-performance enthusiast, the CSF B58 Heat Exchanger is designed to deliver exceptional cooling performance and peace of mind on the road.
