Ensure optimal engine performance for your BMW E9X 325i, 330i, 328i, E8X 128i, or 2009-2010 E89 Z4 with the CSF High-Performance All-Aluminum Radiator. With over five decades of expertise in radiator manufacturing, CSF delivers a product designed for both street and track use, making it an essential upgrade for high horsepower builds and race vehicles that require enhanced cooling performance in demanding motorsport environments. This radiator features a robust 2-Row core utilizing CSF's exclusive B-Tube Technology. Unlike conventional oval "O" type radiator tubes, CSF’s specially engineered "B-tubes" are meticulously formed and brazed over the seam, allowing the use of thinner, lighter aluminum for improved cooling efficiency. This design enhances the heat transfer surface area by approximately 15% compared to standard tubes, achieving the cooling effectiveness of two smaller tubes versus one large tube within the same space. The "B-tube" design also facilitates "dual liquid laminar flow," optimizing thermal performance. CSF incorporates ultra-efficient multi-louvered fins, precisely aligned to maximize airflow through each radiator core. These fin specifications are carefully calibrated and tested for maximum heat rejection efficiency in a wind-tunnel lab, ensuring reliable cooling performance under all conditions. The CSF E9X/E8X radiator boasts a true "Drop-in Fit" design, requiring no modifications for installation. OE-style brackets are CNC machined and welded for superior durability, while inlet and outlet connections are engineered to match OEM specifications, allowing for the reuse of factory hoses or aftermarket options. Trust CSF for the best-performing, highest-quality, and most reliable radiator solution on the market.
