Maybe 15-20 over a older truck intake? Not really sure, My 02 im using this intake on is boosted and I got this intake in a swap for the stock little alternator that I swapped out with a 145 amp one so basically free. Heard they do offer gains so win win for me.

Heres my take on swapping a nnbs intake into a older return style truck. Granted not the cheapest route to take so most won't do it like this...
Used a set of the Holley rails, Magnafuel boost referenced regulator and -6 lines. This truck will be turbo but won't see but maybe 750 so -6 works fine for my setup. can always go bigger being the rails are -8. I ran my fuel lines to where they just plug right into the factory feed and return lines. Today the correct length spacers should come in and the last few pieces to the intake tomorrow so will hopefully have it installed soon.

What's the part number on rails and spacers?

I hate to hyjack your thread, but this made me REALLY want to know something.
EDIT: QUESTION ANSWERED IN "NEW MEMBERS"
so new question
Can somebody identify these intakes for me and is one better than the others?
Looks like the second from the left is best to me!

Int
Any NNBS 4 bolt is better than the old 3 bolt,
they come in Sq or Cat ports. they have
87 mm T/B's and will fit a LS3 90mm T/B.
The tall ugly one is usually the best on big
heavy trucks.
