I would suggest to get the oil filter and fully syn oil from honda, i think oil filter is for Rs830 and oil is Rs2200. For air filter i previously used honda air filter but it chocks the car intake after 1500KM or so as its an oil based filter. Now im using guard filter of rs 350 and its fine for 5000KM. Just get it cleaned by air blower after some time.
BTW if the car is above 20K then you should go for its complete checkup from show room which includes spark plugs, throttle body, balancing and allignment , break service , checking all nuts&bolts etc. This info can also be found in the user manual. They have charged me Rs2500 for labour of previously mentioned things.
