The BMW M3 Radiator by CSF - Triple Pass with a Smooth Satin Finish serves as the perfect cooling solution for your `00-`06 model. Specifically engineered to keep your high-performance E46 M3 operating at optimum temperatures, this all-aluminum radiator is ideal for enthusiasts intent on unleashing their vehicle's capabilities, whether on the streets or on the track.

This sophisticated radiator is equipped with a Triple-Pass Flow Structure, which enables the coolant to circulate across the radiator's core three times before it exits, allowing for the lowest outlet temperatures possible. Integrating CSF's innovative B-Tube Technology, the radiator's core consists of a 2-row structure that achieves unparalleled efficiency by increasing heat transfer surface area by roughly 15% compared to standard tubes. This results in the dual liquid laminar flow that boosts cooling efficiency significantly, ensuring that your engine remains cool under the most demanding of circumstances.
