Skunk2 Ultra Series Street Intake Manifold

Skunk2 Racing's much-anticipated Ultra Street Intake Manifold has finally arrived for the '02-'05 Civic Si and '02-'06 RSX/RSX Type S, as well as any swap using the K20A/K20A2/K20Z1/K24A1 engines or cylinder heads. The Ultra Series is the culmination of years of research and development, resulting in a multi-piece cast aluminum intake manifold that offers advantages only a modular design can provide.

Utilizing the latest in Computational Fluid Dynamics (CFD) 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 lid and optional plenum spacers. In addition to the CFD testing, the Ultra Series Intake Manifold has undergone extensive in-house dyno testing, which has led to a design that is less restrictive, yielding torque and power gains that exceed many of the competitors.

Manufactured from high-grade 356 aluminum alloy for strength and lightweight, Skunk2 Racing's Ultra Street Intake Manifolds are CNC-machined for a precise fit and individually inspected for quality assurance. The Ultra Series Street manifold features a generous 71mm throttle body opening and is constructed with thick walls at the entry, minimizing the risk of breakthrough when port matching.

Intense planning and design went into the plenum to ensure even airflow distribution to all four cylinders under dynamic load conditions. The placement and design of the velocity stacks were rigorously flow tested to guarantee maximum air delivery to the cylinder. Large velocity stack raised bell mouth entries lead to 6.85-inch long intake runners with smooth transitions, allowing the Ultra Street Intake Manifold to move a significant volume of air.

Skunk2 Racing's Ultra Street Intake Manifolds are designed to be used in modified naturally aspirated applications, as well as mild turbo/supercharged setups. The modular 2-piece design offers the flexibility to customize the manifold to suit individual needs, making it a versatile choice for a wide range of performance enthusiasts.
