stichy: What are you trying to achieve by swapping it? Its been widely proven that the stock airbox has more than enough flow for the car to take, even when tuned (bar FI of course!). So if you want performance then dont bother swapping it at all. If you want noise, then short ram intakes (popcharger etc) are the noisiest, but suffer from a bit of heat soak when stationary. CAI elimitate this, but some say the extra length adds extra resistance to the intake charge which slows it down and flows less. Dont know if thats true. Fortunately though being an import, there is no washer bottle for you to remove if you want to fit a CAI.
