So I've got my intake manifold apart right now, and I notice this inside the y-plenum piece:

What's that there for?
Also, until I had it apart I didn't realize that we have a butterfly in the intake manifold. I know with a couple of the Hondas that have butterflies (Integra GSR for example), people remove them, losing a little bottom end but gaining top end. Has anybody taken theirs out?
Thanks guys, just trying to learn more about our cars.
