The original OE radiator from Toyota/BMW is a plastic tank with a single row aluminum core design. While this is generally accepted as good quality and durable, there is always room for improvement. The 4mm fins on the OE radiator made the system fairly efficient for a factory unit. The core itself is one of the biggest limiting factors at only 34mm thick and a single cooling row. With data collected by development partners and race teams, CSF was able to design the ideal High-Performance replacement. The CSF radiator features the latest 5mm fin technology. These fins significantly increase the heat exchange surface area improving overall cooling efficiency and recovery while still maintaining good airflow. The core is much larger than the factory featuring 2-Row 42mm aluminum core. This both increases the fluid capacity of the radiator, and improves the cores ability to dissipate heat. CSF’s Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. The TIG-Welded 100% All Aluminum construction increases the overall strength of the radiator. This improves durability and longevity so you can be confident it will hold up to hard driving conditions. The CSF radiator mounts in the factory location and requires no modifications or cutting. - 2-Row, 42mm Ultra-High-Performance Core - Cooling Tubes with CSF’s Exclusive B-Tube Technology - New 5mm Tall Ultra Efficient Fins with a Multi-Louvered Design for Maximum Surface Area Contact - CNC Machined Mounting Brackets and OEM Style Inlet/Outlet - 100% All Aluminum TIG-Welded Construction - 1-Hour “Mirror Finish” Hand Polish - True Plug-and-Play “Drop-in Fit” Installation Requires Absolutely No Modifications - Individually Leak and Pressure Tested - 2-Year Limited Warranty
