Subaru airbox for sti import

[Scooby Beef]

Hi everyone just need a little help again! I want to take off my piper cross and replace it with a standard air box. I purchased one off ebay thinking that one off a wrx would fit but they don't, someone else is selling one on ebay but its off an sti 2004 but it looks like it would fit from looking at pictures of engines on google. Does anyone know? Thanks
