Intake Manifold Insulator, fits 125cc/150cc GY6 engines. This intake manifold gasket not like GY6 50cc, it doesn't contain O ring. Connects the Intake manifold to the cylinder head.
Mounting holes: 45mm
Diameter: 22.5mm
Mechanics Note: This gasket sits between the head and the manifold. Like the manifold, these will crack over time and leak air causing the engine to run poorly. We suggest you replace these whenever you change the manifold to avoid problems later. Keep these in stock!
