The Skunk2 Ultra Series Intake Manifold represents the ultimate evolution of the intake manifold, and is designed for absolute maximum power. Years of R&D have culminated in a multi-piece cast aluminum (aircraft grade A356) intake manifold that offers advantages that only a modular design could allow. Building upon the performance legacy of the Skunk2 Pro Series Intake Manifold, as well as using the latest in CFD (Computational Fluid Dynamics) software, Skunk2 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. There is simply no better intake manifold on the market if you have a high horsepower build.

Skunk2 Ultra Series Intake Manifolds are made from high-grade 356 aluminum alloy for a strong and lightweight design, and individually inspected for quality assurance. The large 90mm throttle body opening (70mm to 74mm on Street Series models), 87mm velocity stacks, and hi-velocity intake runners with smooth transitions allow the Ultra Series Manifold to outflow the competition. Designed to be used with built, high-horsepower naturally aspirated or forced induction setups, the Skunk2 Ultra Series Intake Manifold helps provide a new level of affordable high-end intake technology for tuners.

Key Features:
  • The ultimate intake manifold for high horsepower builds.
  • Many different sizes are possible by utilizing an available extra spacer. Two base versions are available: a 1.82 Liter (Street Series) version and a 3.5 Liter (Race Series) version. However, each of these versions can be customized by adding one of the available extra spacers we offer. In general, the 3.5 Liter manifold will work for high horsepower N/A and forced induction applications up to 600 horsepower, a 4.5 Liter version is for about 600 to 1000 horsepower, and a 5.5 Liter manifold is recommended for 1000 horsepower and up.
  • NEW: Centerfeed Race Series manifolds now available for the ultimate in power gains. These centerfeed versions channel air right into the center of the manifold and start at a huge 5.0 Liter size, but can also work with an optional extra spacer. They include 3x 1/8" NPT and 3x 1/4" NPT ports. For these manifolds, the 5.0 Liter is recommended for high horsepower N/A and forced induction applications up to 600 horsepower, a 6.0 Liter version is for about 600 to 1000 horsepower, and a 7.0 Liter manifold is recommended for 1000 horsepower and up.
  • Modular design allows for easy disassembly, porting, and plenum volume changes.
  • Made from aircraft grade A356 aluminum alloy (strong and lightweight) and CNC-machined for a precise fit.
  • 90mm throttle body flange (inlet) on Race Series models. 70mm to 74mm on Street Series models.
  • Race Series models feature provisions for secondary fuel rail and injectors.
  • Includes a special THERMAL GASKET to reduce heat transfer.
  • Generously cast runner walls for porting.
  • Raised 87mm velocity stacks - plenty of material to port further.
  • Vacuum tested to ensure quality.
  • Provisions for additional injectors on bottom side of runners.
  • For B Series engine apps, unique mounting flange universally fits all B Series VTEC heads.
  • 6.0" tilted & tapered hi-velocity runners.
  • 4x 1/8" NPT, 3x 1/4" NPT, and 1x OEM AIT ports. Note: some applications will feature different tapped ports.
  • Hi-grade mounting hardware.
Important Throttle Body Notes: Due to the huge 90mm inlet diameter (70mm to 74mm on Street Series models) and unique bolt pattern on this intake manifold, your stock throttle body and other aftermarket throttle bodies will MAY NOT work with it. We HIGHLY RECOMMEND purchasing the throttle body recommended (see the notes on your specific application). For Street Series models, we recommend purchasing a 70mm to 74mm Skunk2 Pro Series Throttle Body, depending on the exact manifold you get and whether you will port it or not.

Other Fitment Notes: Some applications may require additional work or parts since these manifolds do not always come with provisions for sensors in the same areas as your factory manifold. Some plastic trimming and clearancing from other parts might be needed as well.
