Ensure optimal engine cooling for your BMW E46 3-Series or 2003-2005 Z4 with the CSF High-Performance All-Aluminum Radiator, a trusted choice backed by over 50 years of manufacturing expertise. Designed for both street use and track performance, this radiator is essential for high horsepower builds and race vehicles that require enhanced cooling in demanding motorsport conditions. Featuring a 2-Row core with CSF's exclusive B-Tube Technology, this radiator utilizes a specially engineered "B" shaped tube, which significantly improves cooling efficiency compared to traditional oval "O" type tubes. The B-Tubes are expertly formed and brazed at the seams, allowing for a thinner and lighter aluminum construction without sacrificing strength. This design increases the heat transfer surface area by approximately 15%, offering the performance of two smaller tubes in the same space as one larger tube. Additionally, the dual liquid laminar flow created by the B-Tubes enhances thermal management. The radiator is equipped with ultra-efficient multi-louvered fins, precisely aligned to maximize airflow through the core. Each fin specification is meticulously measured and tested in a wind-tunnel lab to ensure maximum heat rejection efficiency. The CSF E46 3-Series/Z4 radiator boasts a true "Drop-in fit" design, requiring no modifications for installation. OE-style brackets are CNC machined and welded for maximum durability. Inlet and outlet connections are designed to match OEM specifications, allowing for the reuse of factory hoses or the option of aftermarket alternatives. Trust CSF, the cooling experts, for the highest quality, best-performing, and most reliable radiator to keep your BMW E46 3-Series or Z4 running at peak performance.
