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.

Skunk2's cast-aluminum Pro Series Intake Manifold for Honda's K-series is a direct-fit replacement for all K20/K24 engines thanks to its unique, patent-pending water neck design and throttle body flange, which is compatible with OEM throttle bodies as well as those as large as 76mm (06+ Civic Si requires adapter, sold separately). The special water neck design eliminates the cutting that would otherwise be involved with some RBC applications (remaining applications require special 1.0 x 11.5-inch NPT plug, sold separately), and the supplied thermal-insulated intake manifold gasket makes for a truly bolt-on installation (no drilling or modifying required). Pro Series manifolds also incorporate an angled-runner design, which allows for ample hood clearance on 88-00 Civics and 90-01 Integras with a K-series engine swap, as well as additional core support clearance on 02-05 Civic Si's.

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.
