Skunk2 Ultra Race Billet Side-Feed Intake Manifold – Honda B Series

Skunk2 Ultra Race Billet Side-Feed Intake Manifold – Honda B Series

Part Number: X307-05-0100

Product Description:

The Skunk2 Ultra Race Billet Side-Feed Intake Manifold for Honda B-Series engines is engineered for serious high-horsepower street and race applications demanding maximum airflow and fuel delivery capability. Designed as the ultimate evolution of the legendary Skunk2 Ultra Series manifold, this billet version features a unique top-side 8-injector single fuel rail configuration tailored specifically for high-output forced induction and race builds.

Constructed with precision CNC-machined billet tapered runners and a modular cast plenum design, the Ultra Race manifold delivers exceptional top-end power while maintaining tunability for a wide range of performance combinations. The tapered high-velocity runners and large plenum volume have been extensively optimized using CFD analysis and dyno testing to maximize airflow efficiency and horsepower potential.

Unlike conventional manifolds, the modular plenum system allows users to increase plenum volume with optional spacers while also permitting additional runner porting for even greater airflow capacity. Designed to support aggressive engine setups, large throttle bodies, and multi-injector fuel systems, the Skunk2 Ultra Race Billet Intake Manifold stands as one of the most capable B-Series intake manifolds available.

Combining limited-production billet construction with race-proven engineering, this manifold offers unmatched performance and premium engine bay appearance.
