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-injector 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. After all of our in-house testing, and also third party dyno testing, we have yet to see a intake manifold that comes close to the performance of the Skunk2 Ultra Race Manifold.

The manifold features the same Skunk2 Ultra high flowing runners and modular plenum design. The modular design allows plenum volume to easily be increased using simple spacers, and the runners can also be freely ported for additional flow and volume. 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.
