Are you looking for something like this? This bike is davespain's. Maybe you can send him a pm for more info. If you just want to go with the dual filters, the pod filter part numbers are: LEFT side RC-2890 and Right Side RC-2900.
The airbox removal kit from newspeedmaster or british customs are only needed if you want to keep the chrome side covers. Or you can cut out you stock air box to fit the pod filters and keep the stock mounting points. Search for "ghetto freak" if you want to go that way.
