If you have a generation 1 MINI, chances are your radiator overflow / expansion tank has a crack in it. And it is pretty likely that if you had one replaced under warranty that it busted again. And Again. This formed and welded aluminum tank is by far the best solution on the market and while the OEM replacement is a cost saving alternative, this badboy is not going to leave you hanging. Ever. This is a dead simple swap to replace. Available in either black or chrome/polished silver.

Fits these MINI models:
R52: 2004-2008 Convertible: Cooper S
