Product Information

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.

I have used many mechanics over the years for the many different types of vehicles in our company fleet and southern BM is one of the very few workshops I can highly recommend. Andrew and his team are also really passionate about their work and it shows.

One of (if not THE most) professional outfits I’ve dealt with - in the auto industry or otherwise. Needless to say, all work was carried out as promised and to an impeccable standard. Thank you Sean and team - you’ve renewed my faith in the auto business!
