Hi guys, this is my first post, and I have a question already. I have a 2003 6.0, and am looking into trading for a 2005 6.0. This truck has an Airaid intake on it, and if I do buy it, I would like to put back the stocker. There is a 2004 box on Craigslist right now, and I was wondering if all 6.0's were the same in that aspect? Thanks!
