The CSF Triple Pass Aluminium Radiator is a high-performance, all-aluminium replacement radiator for the BMW E46 M3. Its triple-pass layout sends coolant across the core three times before it exits for the lowest possible outlet temperature, through a 2-row, 42 mm core with CSF's B-tube technology and 6.5 mm multi-louvred fins. The B-shaped, seam-brazed tubes give about 15% more heat-transfer surface than standard oval tubes in the same space, adding cooling capacity for modified street cars and track use. It is a drop-in fit with CNC-machined quick-connect fittings that take the factory or aftermarket hoses, and it replaces BMW part number 17102228941.
