CSF Bmw E36 M3 / 3-Series High Performance Aluminum Radiator

Optimize the cooling performance of your BMW E36 M3 or 3-Series with the CSF High-Performance All-Aluminum Radiator, backed by over five decades of manufacturing expertise. Whether on the street or at the track, this performance radiator is an essential upgrade for high horsepower builds and race vehicles that demand superior cooling in intense motorsport environments. Featuring a 2-Row core equipped with CSF's exclusive B-Tube Technology, this radiator utilizes a uniquely engineered "B" shaped tube instead of traditional oval "O" type tubes. This innovative design allows for thinner and lighter aluminum construction while enhancing cooling efficiency. The B-Tube configuration increases the heat transfer surface area by approximately 15%, delivering the cooling performance of two smaller tubes while fitting within the same space constraints. Additionally, the dual liquid laminar flow provided by the B-Tubes ensures optimal thermal management. CSF’s ultra-efficient multi-louvered fins are meticulously aligned to maximize airflow through the radiator core, with fin specifications tailored and tested in a wind-tunnel lab to achieve peak heat rejection efficiency. The CSF E36 M3/3-Series radiator is designed for a true "Drop-in fit," requiring no modifications for installation. The OE-style brackets are CNC machined and welded, ensuring exceptional durability. Inlet and outlet connections match OEM specifications, allowing for seamless reuse of factory hoses or aftermarket options. Trust the cooling experts at CSF for a high-quality, reliable radiator that enhances the performance and longevity of your BMW E36 M3 or 3-Series.
