The Skunk2 Ultra-Race Series Billet Intake Manifold, for Honda K and B series engines is the ultimate manifold for high-horsepower street and race engines. Unlike the standard Ultra Manifold, the Billet Ultra was designed for 8-injectors mounted top-side with a single fuel rail.

All Ultra Manifolds feature tapered runners with trumpet profiled entries and plenums that have been designed and optimized using CFD and on the dyno. The short tapered high-volume runners combined with a large plenum favors maximum top end power over lower end power and response. Skunk2 Ultra Manifolds also incorporate a modular plenum design where plenum volume can easily be increased using simple spacers, and runners that can easily ported for additional flow and volume.

After rigorous in-house and third-party benchmark dyno testing, we have yet to test an intake manifold that can match the performance of the Skunk2 Ultra Race Manifold. The versatility of this manifold allows enthusiasts and engine builders to tune the manifold combination to best suit their needs.

The combination of the billet coolness-factor with limited production makes the Skunk2 Billet Ultra Race Manifold special offering.
