i just got a moded airbox from tyga, have a look at there site, id stay with the airbox mod but others here run pods and i know some dont run it at all, you could make your own mod but the tyga one is only a few quid. remeber you may need to set you jest up as youll be sucking more air making the bike run a bit lean.... i havent put mine on yet it goes on at the end of the month with the hrc jet stuff.
