NCY Intake Manifold 30mm EGR Coated (139QMB, GY6)
Description: NCY Intake Manifold 30mm EGR Coated aluminum offers a smooth bore and larger inlet diameter over the stock 24mm Intake Manifold. 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.
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.
