Unless you're lucky enough to find one secondhand or lying about on the floor in a parts department then R-Sport are your best bet. R-Sport can also get you the Inlet Hose and the Airbox Bracket, but be warned the whole lot comes in at ~£200 before you sort out the panel filter and have the battery relocated. It's well woth doing, but it's not a cheap modification...
