go for the ebay CAI man, chances are fitment will be good enough and if not...a little bit of DIY will do the trick.

I was all for dropping stupid money on a brand name intake, but at the end of the day performance-wise... a metal pipe is a metal pipe haha. so just went with a kit similar to that and changed the pod to K & N. sounds good, looks nice in the bay and adds a bit of kick. sure it doesn't have the fan-boy attractiveness of injen..but it cost a 10th of the price.

good luck mate!
