If u have experince with 2009 ff cng kit then why u r re-asking about cng use in 2013 liana, as u know ff cng kit is same from day 1 to last , so the experince is also same. Even great with up model liana !
As for as abid bhai said about ff cng , I am completely disagree, ff cng kit is best kit, u feel no differnce in petrol and cng drive as compared to old 1st gen landirenzo kit. Hell of differce in drive , feel, responce in between ff kit & other kit.
