The NCY polished 33mm intake manifold is an aftermarket intake manifold designed for GY6 125cc to 150cc engines, such as those found on the Honda Ruckus GY6. It connects the carburetor or throttle body to the cylinder head, directing the air-fuel mixture to the combustion chamber.
Its design features a polished internal surface, which:
reduces flow friction
improves airflow smoothness
allows for more efficient cylinder filling
reduces flow disturbances compared to a raw or rough surface
The 33mm diameter is a key dimension: it provides a sufficiently large opening to ensure optimal airflow across the engine speed range of GY6 125-150cc engines, while maintaining adequate air velocity.
