Skunk2 Ultra Street Intake Manifold For Honda B-Series VTEC And Non-VTEC Engines

The Skunk2 Ultra Street Intake Manifold is a high-performance intake manifold designed for Honda B-Series engines, including B16A, B16B, B17A, B18A, B18B, B18C, B20B and B20Z applications. Built to bridge the gap between the Skunk2 Pro Series and Ultra Race intake manifolds, the Ultra Street is engineered for serious street, fast road, track day and high-power forced induction builds.

With its modular two-piece construction, high-flow tapered runners, raised velocity stack entries and optimised plenum design, this manifold delivers excellent airflow while maintaining strong throttle response and improved average power from the mid-range to high RPM. It is recommended for high-performance naturally aspirated engines up to approximately 275 hp and turbocharged or supercharged applications up to approximately 750 hp.

Designed For Honda B-Series Performance Builds

The Skunk2 Ultra Street manifold uses a universal flange design, allowing it to fit both VTEC and non-VTEC Honda B-Series engines. This makes it a versatile choice for Civic, CRX, Del Sol, Integra and B-Series swap applications where improved intake flow, throttle response and future upgrade potential are required.

Compared with the Skunk2 Ultra Race manifold, the Ultra Street version uses longer runners with less taper and a smaller plenum volume. This design helps improve response and average power delivery, making it especially suitable for street and track cars that need usable performance across a wider RPM range rather than only maximum peak power.

Important Fitment Notes

This manifold will not work with the factory throttle body. A minimum 68 mm throttle body is required.

For most fast road and track B18C setups, a 70 mm throttle body is usually the best balanced option, offering strong airflow while maintaining good throttle response and drivability. A 72 mm or 74 mm throttle body may be suitable for more aggressive naturally aspirated builds, high-compression engines, forced induction setups or applications where the tuner specifically requires a larger throttle body.

Additional fuel fittings, vacuum routing changes, throttle cable adjustment, sensor compatibility checks and ECU tuning may be required depending on the vehicle, throttle body, fuel system and engine setup.
