Skunk2 Ultra Street Intake Manifold – B-Series VTEC

The Skunk2 Ultra Street Intake Manifold is a high-performance upgrade engineered for Honda and Acura B-series VTEC engines. Designed using advanced flow analysis and race-proven engineering, it delivers significant gains in mid- to high-RPM power while maintaining excellent throttle response and drivability for street use.

Constructed from high-grade 356 aluminum alloy and CNC-machined for precision, the Ultra Street manifold features a modular two-piece design with a removable plenum lid, allowing for easy porting and customization. Its large 1.82-liter plenum volume and long, raised runners provide an ideal balance between torque and top-end horsepower, making it suitable for naturally aspirated or forced-induction setups.

The manifold accepts throttle bodies up to 74 mm and includes thick runner walls for additional porting flexibility. Each unit is cast with provisions for additional sensors and fittings to support high-performance builds.
