Naraku Intake Manifold 28mm Non-EGR V.2 Coated (139QMB, GY6)

Description: NARAKU V.2 Intake Manifold Coated Non-EGR 28mm offers a smooth bore and larger inlet diameter overstock. Combined, these two assets allow more air and more fuel into your cylinder, giving you more power. Intake manifold upgrades are a must for larger carburetors. It doesn't make sense to install a large carburetor only to have its flow restricted by the manifold. 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. Work on 139QMB 50cc and all GY6-based models, as well as Honda Monkey and Monkey replica engines.

NOTE: 139QMB may require tapered air-flow to 21mm when installing any intake manifold 24mm or larger on its cylinder head. See Naraku Intake Manifold Spacer 24mm (Part# NK200.04). Check local laws before installing them. For off-road use only, not legal use in California's public roads.
