if your looking for gains then get a mugen intake or a dc2 intake! they would work jus as good and look better than the cold air feed in the bumper!
your still going to benefit from a cold air feed no matter what intake it is,i had a cold air feed on my jordan the induction and made a noticeable difference,dont go for the billoin one as you have the cut the bumper for that.Just get a bit of intake style hose and feed it to the middle part of your bumper and add a cable tie thats what i did
^^ Werd. I bought my 9 with one and its been a nightmare trying to get it filled in.
