CSF Bmw E39 M5 High Performance Aluminum Radiator

CSF’s BMW E39 M5 / 540i (MT) High-Performance All-Aluminum Radiator stands as a premier choice for maintaining peak engine performance and cooling efficiency. Leveraging over five decades of expertise in radiator manufacturing, CSF has crafted this radiator to excel both on the street and on the track. Ideal for high horsepower builds and competitive racing, it provides essential cooling performance enhancements for motorsport applications. Featuring a robust 2-Row core, this radiator incorporates CSF’s exclusive B-Tube Technology. Unlike traditional oval "O" type radiator tubes, CSF utilizes specially engineered "B" shaped tubes. These tubes are meticulously formed and brazed to ensure a secure seal, allowing the use of thinner, lighter aluminum for superior cooling efficiency. The innovative design increases the heat transfer surface area by approximately 15% compared to regular tubes, achieving the thermal efficiency of two smaller tubes within the same space as one larger tube. This advancement facilitates "dual liquid laminar flow," enhancing coolant circulation and heat dissipation. Additionally, the radiator employs ultra-efficient multi-louvered fins that are carefully aligned to optimize airflow through the core. Each fin specification is precisely calculated and rigorously tested in wind-tunnel conditions to ensure maximum heat rejection efficiency. This meticulous design ensures that your E39 M5 or 540i remains cool and performs at its best under demanding conditions. The CSF radiator features a true "Drop-in fit" design, allowing for a straightforward installation with no modifications required. OE-style brackets are CNC machined and welded for maximum durability, and the inlet/outlet connections are designed to match original equipment specifications, making it compatible with both OEM hoses and aftermarket options. For those seeking the highest performance and reliability, trust CSF’s expertise to deliver a top-quality radiator that keeps your BMW E39 M5 or 540i running smoothly and efficiently.
