The Skunk2 Pro Series Intake Manifold for Honda B16, B17, and B18C5 VTEC engines is engineered to dramatically improve airflow and mid-to-top-end power compared to the restrictive OEM Honda manifold. Designed for performance street and race applications, this manifold is a direct bolt-on upgrade for B-series VTEC engines, offering proven gains in horsepower and torque across the RPM band.

Constructed from A356 aircraft-grade aluminum, each manifold features an oversized plenum and long, tapered runners that enhance volumetric efficiency and throttle response. The internal geometry has been CFD-optimized for smoother air transition, and the runner-to-plenum entry design has been refined beyond the OEM Type R layout for increased flow and performance.

Each manifold is vacuum tested, black wrinkle powder coated for corrosion protection, and finished with the signature Skunk2 Pro Series nameplate—a hallmark of precision and performance.
