when i had my silvy i lurked on
www.gmfullsize.com. if you want seriousness though, do NOT post in the off-topic section. There are guys there who will book up the cash for a CAI intake set up. others will give you the "an intakes and intake" deal, but you should be able to get a good amount of people talking about it.
