Intake Manifold from Polini, 25mm, for MINARELLI vertical outlet: 25mm with big reed valve.
Basically, manifolds are responsible for the flow of the gas-air mixture to your carburetor. Your original manifolds flow channel is usually smaller than your carburetor - creating a throttle effect, resulting in a hearty power reduction. A tuning manifold corrects this imbalance with a larger diameter, giving you more fl ow and more power - even with your original carburetor. All open manifolds have two things in common: an optimized diameter as well as a shorter and better induction path. Irregardless which sport manifold you choose, your scooter will reward you with a remarkably higher performance.
