Skunk2 K-Series Intake Manifold  307-05-0310  E-mail this product to a friend Skunk2’s Pro Series Intake Manifold for Honda’s K-series (K20/K24) has arrived!   Skunk2 engineers looked to the popular ’06+ Civic Si’s RBC intake manifold for inspiration and went back to the drawing board. Skunk2’s Pro Series Intake Manifold for Honda’s K-series features a larger plenum and shorter, oversized 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 oversized plenum and excessively short runners that would sacrifice mid-range power, the Pro Series manifold was designed for the “street enthusiast” who wants 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 all-new, 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 (adapter included with ’06+ Civic Si kit). 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, included with '06+ Civic Si kit), 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 K-series engine swaps, as well as additional core support clearance on ’02-’05 Civic Si's. Skunk2 engineers use CFD (computational fluid dynamics)—the branch of fluid mechanics that uses numerical methods and algorithms to analyze and solve fluid-flow problems—to perform the millions of calculations required to simulate fluid and gas interactions within complex surfaces such as intake manifolds.
