CSF Bmw E8x/E9x 335I Manual Transmission Aluminum Radiator Upgrade

With over five decades of expertise in radiator manufacturing, CSF stands out as a leader in performance cooling solutions. For BMW E82 1M, E8X 135i, and E9X 335i models, the CSF High-Performance All-Aluminum Radiator is the premier choice for keeping engines cool and ensuring optimal performance on both the street and track. This high-performance radiator is essential for high-horsepower builds and race vehicles requiring enhanced cooling capabilities in motorsport environments. The radiator features a robust 2-Row core equipped with CSF's exclusive B-Tube Technology. Unlike conventional oval-shaped "O" type radiator tubes, CSF employs specially engineered tubes shaped like a "B." These B-tubes are meticulously formed and brazed at the seams, allowing for thinner and lighter aluminum construction without sacrificing strength. This innovative design increases the heat transfer surface area by approximately 15% compared to standard tubes, effectively providing the cooling efficiency of two smaller tubes in the same space as one large tube. The result is a "dual liquid laminar flow" that optimizes coolant circulation. In addition to the advanced tube design, the CSF radiator utilizes ultra-efficient multi-louvered fins, which are precisely aligned to maximize airflow through each radiator core. Each fin specification is carefully measured and tested in wind-tunnel laboratories to ensure maximum heat rejection efficiency, making this radiator an outstanding choice for any performance enthusiast. Designed as a true "Drop-in fit," the CSF 1M/135i/335i radiator requires no modifications for installation, ensuring a hassle-free upgrade process. OE-style brackets are CNC machined and welded for exceptional durability, while inlet and outlet connections are crafted to match the original equipment specifications, allowing for easy reuse of OEM hoses or aftermarket alternatives. Trust the cooling experts at CSF for the best-performing, highest-quality, and most reliable radiators available. Elevate your BMW's cooling performance with the CSF All-Aluminum Radiator and experience enhanced efficiency and longevity in every drive.
