Intake manifold – for reed valve -POLINI 2-stud reed valve- Vespa PK S – Ø=19mm Dellorto SHB economico

Description

Here, as with the rotary vane intake manifold, it is important to select the correct manifold to match the engine housing or chassis mounting.

The advantage of the diaphragm is that the intake tract can be designed more freely. The intake time is no longer limited by the rotary vane. This results in significantly more power and torque, especially in the lower and middle range.
