Skunk2's Pro Series Intake Manifold for Honda's K-series features a larger plenum and shorter, over sized runners when compared to the RBC, and is cast with thicker wall material, leaving room for further porting for high-horsepower applications. Instead of producing a manifold with a significantly over sized plenum and excessively short runners that would sacrifice mid-range power, the Pro Series manifold was designed for the street enthusiast who want more power but doesn't want to sacrifice mid-range performance to get it. The results are improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains.

Pro Series Intake Manifolds offer horsepower and torque gains greater than the popular RBC manifold but without compromising mid-range power output. The design incorporates runners that are similar in length to the RBC's but with larger bores, a special tapered design, as well as a larger, tapered plenum that together preserve mid-range power but increase and accelerate airflow to allow for significant top-end power gains. Pro Series Intake Manifold runner exits are also machined and hand-finished to best match the cylinder head's ports. Skunk2's Pro Series intake manifold's shape and design also increases wave scavenging effects at the engine's ideal operating range, which allow for a broad increase in usable power.
