Nah i myself never had cuore it was my grandparents for some time ago it was used to go and get groceries and such so it was only driven by driver , but i learned to drive on that cuore so i just bought a simota intake and installed it. The mileage got increased by 4km/liter and on motorway it went on 150km/h with intake installed (petrol)
And there is actually only one downside that i dont think it will work with cng but we never had cng in the cuore. And you will have to clean the filter with pressurized air.
