Ideal for turbocharged and naturally aspirated racing applications.
3.5 titre = high power N/A and forced induction applications up to 600 hp
4.5 liters = 600-1000 hp
5.5 liters = 1,000 hp and more

Skunk2 Racing engineers have worked tirelessly to develop the next generation of high performance intake manifolds and are proud to announce the release of the highly anticipated Ultra Series intake manifold. Years of R&D have resulted in a multi-piece cast aluminum intake manifold that offers benefits only a modular design would allow.

Building on the performance legacy of our Pro Series Intake Manifold, and utilizing the latest Computational Fluid Dynamics (CFD) software; Skunk2 Racing has created a three piece modular design that allows for easy plenum disassembly, transfer and 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, resulting in a design that is less restrictive and delivers both torque and power gains for many of the competitors.

The Ultra Series intake manifolds are made from high quality 356 aluminum alloy for a strong and lightweight design, CNC machined for a precise fit and individually inspected for quality assurance. The large 90mm throttle body opening, 87mm velocity stacks and high velocity intake runners with smooth transitions allow the Ultra Series Manifold to outpace the competition. The Skunk2 Ultra Series Intake Manifold is designed to be used with high power built-in, atmospheric or forced induction setups and helps bring a new level of affordable high-end intake technology to the market.
