got mine for $200 brand new. u will have to weld ur intake to make it fit right, There is lost of info, pics, howto's, and lots of other crap mixed in all u have to do is
search rob porter in the classifieds. he had a couple hundred sets of new stock ones at a good price.
you will find a bunch of info on the site about them. probably one of the most popular mods after the basics because you can get them to match up with the stock intake
