Default Intake Manifold

Do the 2024, 117's use a plastic intake manifold? The 24 117's use a 58mm throttle body and new manifold as opposed to the 23 Road Glide ST 117 that used the 55mm and plastic manifold.

Changes to the airbox include 50 percent more volume (4.0 liters), compared to the 107/114 engines. Downstream from there, the intake tract has been completely redesigned with a new aluminum intake manifold that offers a smoother and more direct path into the larger 58mm throttle body (up from 55mm).
