Skunk2 Intake Manifold, Pro Series for H22A/F20B

The Skunk2 Pro Series Intake Manifold for Honda’s H Series engines feature a larger plenum and long oversized runners when compared to the stock dual stage manifold, and are cast with thicker wall material, leaving room for further porting for high-horsepower applications. Instead of producing a manifold with a significantly oversized plenum and excessively short runners that would sacrifice mid-range power, the Pro Series Intake Manifold is designed for the “street enthusiast” who wants more power without sacrificing mid-range performance to get it. The results are improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains.??
