The airbox mods "stickies" are in the "Tech & Performance" forum > "How To" link....see the list.
Here is the direct link.Unfortunately I l;ooked all over, and my air box mod photos were on my free Cox Webspace; which thet deleted without letting me know. http://www.ptcruiserlinks.com/forum/...ication-2.html
On soonercruiser, the 2006 NA, I used the standard AirRaid aftermarket system. http://i305.photobucket.com/albums/n...os/AirRaid.jpg
On the 2006 GT Turbo vert, I did the airbox mod posted as a sticky on the forum. The only different thing that I did was put a small screened port in the wheel well to increase cold air flow.
