Yes sir. Direct bolt on. 10-15hp gain. Great addition for the $$. You'll need the coolant retrofit pipe. Its about $15. About a 3 hour job. Change your oil pressure sending unit while you're there and save yourself a job down the road! They're notorious for going out.

Here is a article on a "HOW TO!" swap it out with a Dyno @ the end to see the results!

Here is another article of the Compare of different manifolds for the LS series motors and their results:

The LS6 manifold is one of the best bolt on mods for our year Vettes, you wont regret installing it and it is pretty straight forward
Thanks,Matt

BTW, you don't have to buy any different coolant pipes. You can grind (or use pliers and snap) some ribs off the bottom of the intake to fit your stock early LS1 coolant lines. I actually prefer this method
