Hello everyone! I'm thinking of buying the Coober airbox lid for my 390 Duke 2020.
But I wonder if the sponge of the airbox lid that came with it is enough to filter out the dirt or dust effectively or not.
Anyone has any idea about this?
I have ordered a stock replacement K&N air filter for my 2014 Duke 390....will I have to do any tunings or have to install the powertronic ecu?? ...I've seen many other reviews and it made me even more confused..what shall I do? will it harm the engine or do any change in performance if I just...
