PRODUCT INFORMATION
THE ULTIMATE COOLING SOLUTION FOR THE E46 M3
The CSF All-Aluminium Triple-Pass Radiator is the ultimate cooling solution for race and high-performance S54 powered E46 M3, including those with high cooling demands found in forced induction and high-power naturally aspirated engines.
This high-efficiency, all-aluminium radiator features an industry-leading core design with CSF's exclusive B-Tube technology along with an ultra-efficient 6.5mm multi-louvered fin height design.
To further the cooling efficiency, the integrated three-pass flow system guarantees the lowest possible outlet temperatures of any upgraded cooling system available for the platform today. Lab tested using CSF's in-house wind tunnel showed heat rejection results approximately 20% more efficient than the OEM unit - enough to keep coolant temperatures fully stabilized during the most demanding driving and high-ambient-temperature conditions.
Direct replacement for BMW part number 17102228941.
