Moroso Aluminium Expansion Tank (E46 M3)
A common problem with both road and race cars is that the E46 M3 plastic expansion tank splits due to age and temperature. Moroso’s precision fabricated aluminium expansion tank is designed as a direct replacement parts and puts a stop to these problems.
Universal expansion tanks cause headaches with fitment, where as Moroso’s comes as a direct drop-in with no modification needed other than to short the two wires for the level sensor, which is no longer applicable. This race-quality piece comes complete with a Moroso 2 bar cap.
Perfect in combination with a CSF Triple-Pass Radiator.
