Alittle ls6 intake buying help
The other is #12573572
Whats the difference? I'm going to do bbk lt headers with this intake so I'll be deleting my air/erg..So the one off the camaro looks about right I think.
If anyone wants to take a look and see if they or which one is worth it, it would be greatly appreciated...(I have a 99 TA a4) I would also need to buy a intake manifold coolent pipe kit for the change, anything else I should need for the complete install of just the intake? Seems like I'd save money as oppososed to buying it off the ws6 store new for 550$ just for the intake..
Thank you..
Be careful about your oil sending unit, some replace it during the swap.
I would also port your tb.
You can literally do an intake swap in 45 minutes, I'd give a first timer hour an half. Few simple tools.
Are you going with an ory? Cutout? Muffler?
12573572 is a corvette part. So it didn't need the cable bracket and it doesn't have the threaded bosses for those bolts. You will need to rig something up on this one to make it work. Or destroy your stock one and steal those bosses.

If someone was selling an SLP LS6 intake that has been modified to fit an f-body or have an EGR then I'm sure they would say that when they were selling it.
I'm sure that if someone were to buy a standard LS6 #12573572 manifold, it would have the cable bracket boss.
SLP would buy manifolds from G.M. and then modify them by installing Swageloc fittings for EGRs. That was the only mod made to the manifold. I know what I'm talking about because I have one. SLP stopped selling these manifolds a while back. Now I think the only manifold they sell is part of a package including heads.


Also for a little FYI , you have a foul mouth.

How stupid would SLP be for selling you a $600 stock intake that you had to work on before you put in on your car.
I had a CTSV that I sold the intake off of and I can tell you that it was a 3572 with no bosses. I also know people who have had to modify there's.
I can't help myself. This guy bought a modified part so that makes him an expert on how it came stock.
