MINI Cooper S Turbo Diverter Valve for all Turbo MINI. Works for both N14 and N18 engines in the whole R car line (R55-R61). For several years now the stock diverter valves have been a common part to fail. MINI has updated a this part a few times now and this is the latest and best one yet. This diverter valve is a direct replacement for your failed valve. The new design may also give you a slight increase in performance, but we know for sure that it will fix the problem of boost lost. Make sure you have a check engine light for this problem.

Our Countryman had lost it's oomph. It happened slowly over time so, it was something that went unnoticed for a while. I started to figure it was boost related and saw some mention of the diverter valves going bad. I swapped the diverter valve to this new type and wow! Night and day difference. It felt like a whole different car. Really great to have one part make a big difference.
