do what i did.
go on ebay and find a cone filter mas adapter from a guy named redfueldlx or somethign like that....its like $40 shipped at the most!
buy a $20 cone filter from autozone, or equilivant
leave the bottom of the air filter box on to bring in cold air to the filter and install.
boom KKM LIKE SET UP FOR A FRACTION OF THE PRICE.
i like my set up it really has a few more ponys after doing that......just a few not like the amount of HP you get when putting on a POWERED BY HONDA STICKER.....or A BIG WING, but it is noticable power increase.
