Cold Air Intake options

[ClassicAU]

Now that I have the air flowing out a bit better, I am looking to get some more air coming in! What is available for the AU I6? All I have at the moment is a K&N filter and Tickford snorkel. I was thinking of changing the intake piping from the air box to something with a bit more flow. If I do this, I am not sure what I need to do about the breather port thats at the back of the rocker cover? Can I just put one of those little filters on it? I was also considering a pod filter inside the standard air box. Would that make any difference at all? If anyone has any photos of their setup, that would be great!
