Skunk2 Ultra Race B-Series Side Feed Billet Intake Manifold

The Skunk2 Ultra-Race Series Billet Intake Manifold is engineered for high-horsepower street and race applications, specifically for Honda B series engines. This Billet Ultra version supports 8-injectors mounted top-side with a single fuel rail, differentiating it from the standard Ultra Manifold. All Ultra Manifolds feature tapered runners with trumpet profiled entries and plenums optimized through CFD and dyno testing. Its design, characterized by short tapered high-volume runners and a large plenum, is optimized for maximum top-end power. The manifold's modular plenum design allows for increased plenum volume using spacers, and runners can be ported for additional flow. Skunk2 claims this manifold offers best-in-class power increase. It includes a 90mm throttle body flange with a standard 5.0 Ford bolt pattern and a thermal gasket.
