This 5.2 liter, 6 cylinder engine delivers up to 180 hp and runs on minimum 95 oct mogas!

With only 108 kg (238 lb) you will love this engine.

We are pleased to inform you that the NEW UL520i (from 223501 ) engines have an updated ECU map which will allow the engine to run on MoGas 91 RON fuel . This possibility will open up many doors in regions where customers are struggling to obtain higher octane fuel .
IMPORTANT REMARK: for 520i engines with a serial number lower than 223501, you still need to use minimum 95 RON fuel (labelled as 91 AKI fuel in USA / Canada). (Contact your dealer if you would like to update the ECU map in order to be able to run your 350i / 520i engine on 91 RON)
