![]() Skunk2’s all-new, cast-aluminum Pro Series Intake Manifolds for Honda’s K-series engines are a direct-fit replacement for all K-series engines (excluding '06-'10 Civic Si) thanks to their unique, patent-pending water neck designs and throttle body flanges, which are compatible with OEM throttle bodies as well as those as large as 76mm. The results are improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains. Instead of producing a manifold with a significantly oversized plenum and excessively short runners that would sacrifice mid-range power, Pro Series manifolds were designed for the “street enthusiast” who wants more power but doesn’t want to sacrifice mid-range performance to get it. We have test fit this manifold in a K-swapped EG civic (see photos).Skunk2's engineers looked to the popular '06-'10 Civic Si’s RBC intake manifold for inspiration when developing our Pro Series Intake Manifold for the '02-'05 Civic Si and '02-'06 RSX/ RSX Type S, and/ or any swap using the K20A/ K20A2/ K20Z1/ K24A1 engines or cylinder heads and we are happy to say they have finally arrived!Įach of Skunk2’s Pro Series Intake Manifolds for Honda’s K-series engines feature larger plenums and shorter, oversized runners when compared to the RBC, and are cast with thicker wall material, leaving room for further porting for high-horsepower applications. This manifold offers some good regained clearances over the RBC/RRC manifolds. Note: Because of its compact size and lower arching angle compared to the Honda RBC/RRC intake manifold, there are no modifications required for fitment. Note: Throttle body flange is based off the 02-06 RSX Type-S / 02-05 Civic Si Not compatible with K24Ax (RBB/RAA) or K20Z3 (RBC) style heads due to missing water port these heads require. Fitment is for K-series PRB (RSX) style head.8.72" long runners w/raised velocity stacks (portable). ![]() Designed to be used with modified street applications and mild turbo setups, the Skunk2 Ultra Series Street Intake Manifold provides a new level of affordable high-end intake technology to the marketplace. The large velocity stack and raised bell mouth entries lead to long, 8.72”, intake runners with smooth transitions allowing the Ultra Series Street Intake Manifold to outperform the competition. Placement and design of the, rigorously, flow tested velocity stacks ensure maximum delivery of air to the cylinder. The 1.82L plenum distributes even airflow to all four cylinders under dynamic load conditions. ![]() The Ultra Series Street Intake Manifold features a 71mm throttle body opening and is constructed with thick walls and entry, minimizing concerns of breakthrough when port matching. Each manifold is CNC-machined for a precise fit, and individually inspected for quality. Ultra Series Street Intake Manifolds are manufactured from high grade 356 aluminum alloy for light weight and added strength over sheet metal manifolds. ![]() In addition to CFD testing, the Ultra Series Intake Manifold has undergone extensive in-house dyno and on-car testing which has led to a design that is less restrictive, yielding both torque and power gains well over many of the competitors. Proudly presented by the Skunk2 Racing engineering team, the Ultra Series is years of research and development, culminated in a multi-piece cast aluminum intake manifold that offers advantages that only a modular design could allow.īuilding upon the performance legacy of the Pro Series Intake Manifold, as well as using the latest in CFD (Computational Fluid Dynamics) software Skunk2 Racing has created a two-piece modular design that allows for easy disassembly, porting, and plenum volume changes through the use of a removable plenum and optional plenum spacers. The much anticipated K-Series Street model is now available. Skunk2 Racing Ultra Street Series Intake Manifolds are the next generation of high performance intake manifolds. ![]()
