16-2520 G manifold, std 4.650 inch cylinder

If you are running a Super G carburetor on a 1986 to 2003 XL Sportster with stock engine dimensions, this S&S intake manifold is the correct fitment. Sized at 341, it is designed to work with the standard 4.650-inch cylinder height found on these Evolution Sportsters. The Super G is a serious carburetor, and this manifold ensures it has a clear, unobstructed path to the intake ports. S&S manufactures these manifolds to exacting tolerances to prevent the vacuum leaks that can plague lesser components. It is a straightforward, high-performance upgrade that provides the solid foundation needed for reliable fueling and maximum power on your Evo Sporty.
