Skunk2 Racing Ultra Series Intake Manifolds are the next generation of high performance intake manifolds. The much anticipated K-Series Street model is now available. 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. Building 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. 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. Ultra Series Street Intake Manifolds are manufactured from high-grade 356 aluminum alloy for light weight and added strength over sheet metal manifolds. Each manifold is CNC-machined for a precise fit, and individually inspected for quality. 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. The 1.82L plenum distributes even airflow to all four cylinders under dynamic load conditions. Placement and design of the, rigorously, flow tested velocity stacks ensure maximum delivery of air to the cylinder. The large velocity stack and raised bell mouth entries lead to long, 8.72 in., intake runners with smooth transitions allowing the Ultra Series Street Intake Manifold to outperform the competition.
