Whether for performance street driving or competitive racing, this manifold provides significant gains in both top-end and mid-range power, helping enthusiasts unlock their engine’s full potential while maintaining drivability. It is compliant with EPA standards and is CARB exempt, making it suitable for use in various regions without restriction. The design also eliminates secondary butterflies, improving airflow and throttle response, while the three flange options ensure a perfect fit for a wide range of B-series engines. With its proven track record and superior craftsmanship, the Skunk2 Pro Series Intake Manifold is an excellent upgrade for Honda and Acura enthusiasts seeking reliable power improvements and a high-performance edge.
