It appears there's various part numbers for the LS6 intake. Can anyone tell me if 12573572 is an LS6 intake? Can anyone tell me all of the part numbers for the LS6 intake?
Thank you.

its easy to tell weather or not its a LS6 intake.. the LS6 intakes are flat on the bottom.. LS1 are round on the bottom where the valley cover is.

One other thing I just remembered get the LS6 intake without the EGR provision which is not needed on the C5. That was for the 98-2000 Camaro. I don't remember the part number but I think its the same 12573572 ( also used on 98-00 Camaro) number I believe this intake (part #) comes with and without the provision for the EGR valve.

most ls1 intakes have the hole right behind the throttle body, expect the corvettes. you could play a ls1 intake as a ls6 to the right person haha! also like people have stated, ls6s are flat on the bottle.

here are the part numbers for ya.
97-00 LS1 Manifold #12556333
01-02 LS6 Manifold #12561182
03+ #12573572

Thank you for the information. I've been trying to buy one on eBay. Some of the pictures provided don't show the flat bottom and it's about impossible to tell from the top side. I'm a little shy about buying something I'm not 100% sure of. So again, thanks.

So theLS1 is rounded on the bottom and the LS6 is flat???!!!!

Specifically, the 97-2000 LS1 intake is rounded on the bottom, and the 2001-04 LS1/LS6 intake is flat on the bottom.

Yep, LUCKY put the reply straight.

2001+ are all LS6 style intakes. If your LS1 is a 1997 - 2000 it has the hump bottom
