hey guys just looking at the airbox is there any mods that can be done to it?? looks like a very small intake hole at the front. I will be using an air filter so the mod would just be to the housing

leave as it is mate, the NC's can be like spoilt brats when you fettle with the induction system.

Standard filter works really good for most circumstances, any other airfilter or airbox mod will make it a pain in the arse to get the fuelling right throughout the rev-range and won't really give you any gains.
