The Skunk2 Ultra Race Series billet intake manifold is a CNC-machined, three-piece modular manifold for Honda/Acura K-Series engines, developed with CFD on the Pro Series platform. The removable plenum and optional volume spacers let you tune plenum volume (1L spacer ~600hp, 2L ~1000hp), and the short, tapered, high-volume runners favor maximum top-end power on high-RPM and forced-induction builds. This is the side-feed (fuel rail) configuration.
