NCY Intake Manifold - 28mm Performance; GY6 Engines

NCY 28mm performance intake manifold for 125/150cc GY6 engines. NCY's manifolds offer a smooth bore and larger inlet diameter over stock. Combined, these two assets allow more air and fuel into your cylinder, resulting in more power. Intake manifold upgrades are a must when installing a larger-diameter carburetor. Why restrict your flow when you want your scoot to go? Larger manifolds can make a noticeable power increase on their own, and provide a choice option over the standard rubber manifolds. Long-lasting parts, and more power. It's a win-win. Note: When installing a larger carburetor and/or intake manifold, please verify the engine side diameter of the carburetor for proper fitment into the manifold.
