The Skunk2 Pro Series Intake Manifold for Honda H22A and F20B VTEC engines is engineered as a high-flow performance replacement for the restrictive OEM intake manifold. Designed to maximize airflow, increase power, and improve throttle response, this manifold delivers significant midrange to top-end horsepower gains — making it ideal for both naturally aspirated and turbocharged applications.
Precision cast from aircraft-grade A356 aluminum, the manifold features an oversized plenum and long, tapered runners that create a powerful venturi effect, improving air velocity and cylinder filling at higher RPMs. Each unit is vacuum tested to ensure leak-free performance and finished with Skunk2’s signature Pro Series nameplate for a race-ready appearance.
With a 70mm throttle body opening (port-matchable up to 74mm), this manifold supports larger throttle bodies such as Skunk2’s Pro Series line for maximum airflow potential. It eliminates restrictive OEM components like IAB butterflies and EGR passages, reducing turbulence and simplifying the design for peak efficiency.
