I saw these on ebay. I asked the seller if everything in the pic was included(fuel rail, throttle body) and he said yes but only warranty the intake manifold. They are buy it now or best offer, I bought one for $150 shipped.

Cathedral port:
Intake Manifold 4 8L Fits 10 15 Express 2500 Van 274835 | eBay

Rectangle port:
07 08 Cadillac Escalade Intake Manifold 232463 | eBay

 

Damn that's a deal. I paid $200 for mine.

It's a direct swap minus the xlink. The stainless rails means it's for flex fuel and if your NBS is already flex fuel, everything plugs in.

 

Hey guys, I don't mean to hijack but it's better than starting a new thread lol. I just want to be sure I have the right info before buying a nnbs intake. Does it matter which engine it came from? ie: 4.8, 5.3, etc I'm looking to put one on my '07 Classic 4.8

 

4.8 or 5.3 , doesnt matter they are the same.
Only thing that matters is whether you have cathedral port or rectangle port.

 

That's a million dollar question haha I've only had the truck a couple months

 

It will be a cathedral port, as the rectangle Port heads MUST be installed on a 4.000" bore minimum. no 4.8-5.3's came with rect. Port heads/intake. Hope that helps

 

That was my first guess after a quick Google search, thanks a lot guys I really appreciate the help and again sorry for hijacking lol, now back on topic

 

Looks like theyre sold out of both of them..
