IAB - Intake Air Butterflies;
- A valve that opens and closes to switch between two available passages in the intake manifold. This is done to allow the use of a longer runner at low RPMs for increased torque and a short runner at high RPMs for more power. Found on A20A, GSR, and H22A intake manifolds.
