Compared to throttle-body injection (TBI) systems, what are the advantages of port fuel injection systems?

What will be an ideal response?


A major advantage of port fuel injection over TBI is that engineers can design intake manifolds with long, tuned runners. This results in higher engine torque at lower engine speeds. The intake manifold can be tuned this way because it only carries air, not air and fuel like TBI manifolds.
