Speedwerx has a aluminum piece that replaces the stock plastic piece where the flexable hose attatches to the air box...which allows more air flow. D&D has bullseye kits...pretty must you drill a hold in the air box and install the "bullseye".
Fast600,
Inlet tube # 1670-315, you will need 3 screws # 8047-397 to hold it down. You have to trim about quarter of an inch out of the hole to get it to fit in. Only fits in one way correctly. When finished it looks very nice, stock looking ! I put a little bead of silicon sealer around mine to make sure I didn't have any air leaks. I don't think you would have to but I did on mine.
