Skunk2 Ultra Series B Series VTEC Street Intake Manifold - Black Series

The engineers at Skunk2 Racing have worked tirelessly to develop the next generation of high performance intake manifolds and are proud to announce the release of the much anticipated Ultra Series Intake Manifold. Years of R&D have 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 our Pro Series Intake Manifold, as well as using the latest in CFD (Computational Fluid Dynamics) software; Skunk2 Racing has created a three-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. Detailed and meticulous planning went into every aspect of the Ultra Series Street Intake Manifold. Ultra Series Street Intake Manifolds are manufactured from cast-aluminum high-grade 356 aluminum alloy for lightweight yet added strength over sheet metal manifolds. Each manifold is CNC-machined for a precise fit, and individually inspected for quality assurance. The Ultra Series Street manifold features a generous 74mm throttle body opening and is constructed with thick walls and entry minimizing concerns of breakthrough when port matching. Intense planning and design went into the plenum (1.82L plenum volume) to distribute even airflow to all four cylinders under dynamic load conditions. Placement and design of the velocity stacks were rigorously flow tested to ensure maximum delivery of air to the cylinder. Large velocity stack raised bell mouth entries lead to long 221.5mm intake runners with smooth transitions allowing the Ultra Series Street Intake Manifold to outflow the competition.

Product Overview

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. 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 lid and optional plenum spacers. In addition to 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 both torque and power gains well over many of the competitors.

Skunk2 Racing Ultra Street Intake Manifolds are cast-aluminum, manufactured from high-grade 356 aluminum alloy for strength and lightweight. Each manifold is CNC-machined for a precise fit, and individually inspected for quality assurance. The Ultra Series Street manifold features a generous throttle body opening and is constructed with thick walls at entry, minimizing concerns of breakthrough when port matching. Intense planning and design went into the plenum to distribute even airflow to all four cylinders under dynamic load conditions. Placement and design of the velocity stacks were rigorously flow tested to ensure maximum delivery of air to the cylinder. Large velocity stack raised bell mouth entries lead to intake runners with smooth transitions allowing the Ultra Street Intake Manifold to really move some air!

Skunk2 Racing Ultra Street Intake Manifolds are designed to be used in modified naturally aspirated applications as well as mild turbo/supercharged setups.

Note for Australian and European Markets

Unless otherwise stated, this product may be engineered for use in Left-Hand Drive vehicles. Steering components, pedals, shifters, linkages, wing mirrors, instrument clusters, panhard rods/traction bars, drag links, brake boosters, brake or clutch lines, accelerator cables, heater cores, some master cylinders and adjacent parts can vary between LHD and RHD configurations. In some models compenents such as windscreen wiper arms, motors and linkages could differ in their size and orientation. Items such as floor mats & dash mats may have differences in their structure around the front row (or padding in different locations). In many cases items are identical depending on the design of the vehicle and part, but may have differing mounts, lengths or bolt patterns. Carefully review the product images and details to ensure suitability for your vehicle, or contact StreetFX support if you are unsure. Returns are not accepted for special order products.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.
