Nissan air filter box.

Hello, Iposted a similar post on another section of the forum but as I have got no reply I think that I may have put it in the wrong place. I have the excuse of being well over 80. I require a air filter box for my micra. It is a 1L petrol engine registration is 52 plate. First registered 05/11/2002. I have looked at ebay and there are some there but I do not want to buy the wrong one so can anyone tell me if all the k11 micras use the same filter box. Also is there other types of air filter that I can fit. Thank you all.
