GY6B Intake Manifold

GY6B Intake Manifold for 150cc ZNEN Engines

This GY6B intake manifold is made for 150cc ZNEN 4-stroke engines used in a range of scooter models. It connects the carburetor to the cylinder head, where it plays a key role in delivering air and keeping the engine running properly. If you notice cracks or dry rot, it is time to replace it. Like other parts in the scooter fuel system, keeping this manifold in good shape helps your scooter run reliably.

Why the Intake Manifold Matters

The manifold has two vacuum points, both of which support normal engine operation. It is the only point where the carburetor mounts, so its condition has a direct effect on how the scooter performs. Checking it regularly makes it easier to spot wear early and avoid problems while riding.

Fitting the Part

This manifold is designed to replace the original one directly, so installation is simple. The carburetor-side inner diameter is 23mm and the bolt hole spacing is 45mm, which keeps the carburetor securely attached. Before fitting, look over your old manifold for any damage.
