Further Information
CSF delivers over 5 decades of cooling expertise with this High-Performance All-Aluminum Radiator engineered specifically for the BMW E30 M3. Built for street and track duty, this radiator combines advanced thermal technology with precision engineering to keep your engine running at peak performance during high-horsepower builds and motorsports applications.
The radiator features CSF's exclusive B-Tube Technology, where specially engineered B-shaped tubes are carefully formed and seam-brazed for superior strength compared to conventional O-shaped welded tubes. This innovative design increases heat transfer surface area by approximately 15% while allowing thinner, lighter aluminum material—delivering the cooling efficiency of dual tubes within the same physical space and enabling dual liquid laminar flow.
Ultra-efficient multi-louvered fins are precisely aligned and wind-tunnel tested to maximize airflow and heat rejection across the 1-1/4" core.
