Compared with stock parts, it has a wider inlet, which lets more air and fuel reach the cylinder. It is a logical choice when fitting a bigger carburetor. You can find it among our \u003ca href=\"\/collections\/gy6-scooter-parts\"\u003eGY6 scooter parts\u003c\/a\u003e, and it is a practical option for raising engine output.\u003c\/p\u003e\u003ch3\u003eBuild and Layout\u003c\/h3\u003e\u003cp\u003eThe manifold is cast from aluminum and finished with a PTFE coating, which helps it hold up to wear over time. It includes one vacuum line fitting for a tight, reliable hookup. Its larger bore allows more air to pass through, which can translate into a noticeable gain in power.\u003c\/p\u003e\u003ch3\u003eDeciding to Upgrade\u003c\/h3\u003e\u003cp\u003eThink about replacing the factory manifold if you are moving to a larger carburetor or want more from your engine. Compared with standard rubber units, this one flows better and is more durable.
