The old LS1 intake with the EGR setup is 12560688.
The Stock 2001-2002 F-body LS6 is 12561184.
The Z06 LS6 is 12573572.
These are the numbers stamped on the manifold

but from the 2nd. pic. it looks lick a ls1, because of the coolant line
that runs between the two heads and Ts. off and gose under the intake,
i dont think that the engines that the ls6 intake came on had that coolant line.
they had the newer coolant line that did not T. off and go under the intake.

Confusing ... I have a '99 T/A and my wife has '02 T/A. I just physically looked at both T/A's and my intake is GM Part# 12556333. Her's is GM Part# 12573572. Neither intakes have been chnaged. DaleMX just said that GM Part# 12573572 is the intake number for the LS6 Z06 ... not so in this case. Is there an accurate list of GM Part #'s that tells what the real deal is for each year model? Did the assembly plant just put different intakes on the later year 2002's because they ran out of the regular 2001-2001 intakes? [... maybe since they weren't going to make F-bodies anymore.]

Production convenience maybe???? Yeah, I fgured they may have had an overage of LS6 intakes and maybe have used them up on the 2002 F-body's. Or maybe they just figured 2002 being the last production year ... they would just produce the LS6 one across the board. Thanks to all who have replied. If anyone else has any inout to this thread, please provide it. Again, thanks to everyone.

There are a few stories of VERY early (7/00) production 2001's having the older intakes... but VERY few.

So many different numbers That would mean they simply kept changing the part numbers depending on which type vehicle or year model the vehicles were? I'm seeing several folks here with different GM Part #'s on their 2001 and 2002 F-body's and 'Vette's. Anyone know if this might be correct?
