| "in Tube" type Pipercross filters are £20 to £25. They fit any air tube that have runners fitted, Standard, carbon, unobtainium etc.
If you have no runners in yer air tubes theirt are alternatives to under tank types, i.e the ones that go over the inlet to the airbox. They ain't £300 either. Seen em on an aussie website and no doubt someone brings em into the UK.
