16-2598 G manifold OEM & S&S heads, size 417

Feeding a 124-inch Evolution or a 1999 to 2005 Twin Cam B engine requires a manifold that can handle serious volume. This S&S size 417 manifold is designed for engines with a 5.013-inch cylinder length and comes equipped with a MAP sensor hole for proper electronic integration. It is intended for use with Super G carburettors and fits both OEM and S&S cylinder heads. The cast construction is exceptionally durable, ensuring that the intake tract remains stable under the high vacuum and heat cycles of a massive stroker motor. It is an essential component for any professional-grade engine build, providing the exact geometry needed for maximum airflow and reliable sealing.
