You would be best just adding the lower snorkle from an XR8/F6 onto it mate. Much cheaper and has the same effect. I did the same thing to my BA and made a much better induction note with a bit of flutter when you back off. BTW that plazmaman one is a turbo side intake which would need a retune. *EDIT* Not sure if retune would be needed but could interfere with stock intercooler piping
