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 dis-assembly, 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 Intake Manifolds are made from high-grade 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 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 affordable high-end intake technology to the marketplace.

• Ideal for turbocharged and naturally aspirated race engine build applications
• 3.5L = high horsepower N/A & Forced Induction engine build applications up to 600hp
• Skunk2 Ultra Series 90mm billet throttle body available separately

Vehicle Applications

The Ultra Series K-series intake manifold is race application and is NOT a direct fit for the 02-05 Civic Si or 02-06 RSX vehicles (both use PRB style heads). However, Skunk2 tells us the manifold will fit the following K20 or K24 swapped vehicles (using a PRB style head) along with the either of the following components:

 

• Karcepts or  K-Tuned A/C & P/S Eliminator Kit (KP-UNV-385)
  OR
• Electric water pump w/water block off plate (K-tuned kit# KWP-PKFJ-204)
  
  Will then fit these tested K-swapped vehicles:

• 92-95 Civic
• 96-00 Civic
• 94-01 Integra
