For the ultimate cooling performance of your BMW, consider the BMW 135i Radiator by CSF. This high-performance all-aluminum radiator with B-Tube Technology is expertly crafted to maintain your engine's optimal temperature. Available in a smooth satin finish, it fits BMW models from 2008 to 2011 and promises to be a trusted component for both street use and high-demand motorsports.

This radiator stands out because it features a 2-Row core incorporating CSF's exclusive B-Tube Technology. Unlike conventional oval "O" type radiator tubes, the B-Tube design is stronger and more efficient, allowing for dual liquid laminar flow and increased heat transfer by approximately 15%. The specially engineered tubes are formed and brazed to seal efficiently and are constructed with thinner and lighter aluminum, enhancing heat rejection and airflow. Complementing the advanced tube design are multi-louvered fins, precisely aligned for maximum airflow and cooling capability, ensuring optimal temperature regulation for your BMW's engine.
