I just bought the new Fast 102 mm intake for my 2005 ls2 c6 got the unit shipped to my door for $799.00 needed to upgrade since the stock intake on the Ls2 sucks a great improvement in gains from what the guys at LG Motorsports tell me from actual dyno #s on cars they did work on, my car already has all the bolt ons you can put on already, getting it put on in a few days will let you know the gains soon.
