Pyaray Bhai!
Japan abb Naam ka hireh gia hai......
Geniune Honda Thailand parts are coming as Honda City do not exists in Japan..... We are following Thailand even for accord too...Only the latest City is launched by the name of Grace in Japan as we all know....
Though you are right that Nissin used to be OEM supplier but till 2005/ 2006, not now .... I put Nissin Pads in 2008 in my 2005 Civic EXi...... but for Honda City current generation i confirmed during my City's Disc Pads replacement that Nissin do not provide for Current H City. To get Asuki is another issue of authenticity....
So better to get OEM pads from 3S or from after market reliable patent Honda Spare parts shop which provides OEM parts in less Price than 3S.... Like Bilal Autos , Sajjad Autos & Honda Palace in NilaGumbad Lahore.
I am some how 100 satisfaction and trust on Bilal Autos.
