CSF Bmw E8x/E9x Automatic Transmission Aluminum Radiator Upgrade

With over five decades of experience in radiator manufacturing, CSF has established itself as a leader in high-performance cooling solutions. For BMW E82 1M, E8X 135i, E9X 335i, and E89 Z4 models, the CSF High-Performance All-Aluminum Radiator is the ideal choice for maintaining optimal engine temperatures and enhancing performance on both the street and the track. This radiator is a crucial upgrade for high-horsepower builds and race vehicles that demand superior cooling capabilities in motorsport settings. The radiator features a robust 2-Row core integrated with CSF's exclusive B-Tube Technology. Unlike traditional oval-shaped "O" type radiator tubes, CSF employs specially engineered "B" tubes that are meticulously formed and brazed at the seams. This innovative design allows for the use of thinner and lighter aluminum materials while ensuring enhanced cooling efficiency. The "B-tube" configuration increases the heat transfer surface area by approximately 15% compared to standard tubes, effectively achieving the performance of two smaller tubes within the same space as one large tube. This design promotes "dual liquid laminar flow," optimizing coolant circulation for superior cooling performance. In addition to the advanced tube design, CSF incorporates ultra-efficient multi-louvered fins that are carefully aligned to maximize airflow through the radiator core. Each fin specification is rigorously measured and tested in wind-tunnel laboratories to ensure maximum heat rejection efficiency, making this radiator an exceptional choice for performance enthusiasts. Designed as a true "Drop-in fit," the CSF radiator requires no modifications for installation, allowing for a seamless upgrade process. OE-style brackets are CNC machined and welded for unparalleled durability, while inlet and outlet connections are engineered to match OEM specifications, ensuring compatibility with existing hoses or aftermarket options. Rely on the cooling experts at CSF for the highest-performing, most reliable radiators on the market. Upgrade to the CSF All-Aluminum Radiator for your BMW and experience unmatched cooling efficiency, enhanced performance, and longevity in every drive.
