307-05-0500 - Skunk2 Racing Ultra Street Intake Manifold - Honda B Series (All)

The Skunk2 Ultra-Street Series Intake Manifold for Honda B16A/B17A/B18A/B18C/B20A Engines is a high flowing manifold that bridges the performance gap between Skunk2s Pro Series and Ultra-Race series manifold. The manifold is designed with a universal flange that will bolt up to all VTEC and Non-VTEC B-series engines. All Ultra manifolds feature tapered runners with trumpet profiled entries and plenums that have been designed and optimized using CFD and on the dyno. When compared to the Skunk2 Ultra Race, Ultra Street runners are longer with less taper, and the Ultra Street plenum has a smaller volume; this combination may limit ultimate peak power in favor for better response and better average power from mid to high.

The Skunk2 Ultra Street Manifold is cast as a two-piece manifold from aircraft grade A356 aluminum. The modular design means the plenum volume can easily be increased using simple spacers, and the runners can 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.

Recommended for high-performance naturally aspirated engines up to 275hp, and turbo/supercharged engines up to 750hp

Each manifold is vacuum tested, and finished-off with our Signature Skunk2 Pro-Series nameplate.
