Upgrade Your BMW E36 M3 / 3-Series with CSF's High-Performance Radiator

When it comes to keeping your BMW E36 M3 or 3-Series running cool under pressure, CSF has over 50 years of expertise in radiator manufacturing. This High-Performance All-Aluminum Radiator is engineered for serious performance, whether you're cruising the streets or pushing your limits on the track. If you're running a high horsepower build or a dedicated race vehicle, this radiator is essential for enhanced cooling performance.

Innovative B-Tube Technology

The CSF radiator features a 2-row core with exclusive B-Tube Technology. Unlike traditional oval-shaped "O" type tubes, CSF’s specially designed "B-tubes" are not only lighter but also provide superior strength and cooling efficiency. This design increases the heat transfer surface area by approximately 15%, allowing for dual liquid laminar flow. The result? Maximum cooling potential in a compact space.

Precision Engineering for Optimal Performance

Each radiator is fitted with ultra-efficient multi-louvered fins, precisely aligned to maximize airflow through the radiator core. Tested in wind-tunnel labs, the fin specifications are tailored for each application, ensuring exceptional heat rejection efficiency.
