Skunk2 Ultra Race Intake Manifold For Honda D-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 multipiece cast aluminum intake manifold that offers advantages that only a modular design could allow.

Following our Ultra Race B & K Series Intake Manifolds, as well as using the latest in CFD (Computational Fluid Dynamics) software; Skunk2 Racing has created a threepiece 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 inhouse dyno and oncar 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 highgrade 356 aluminum alloy for a strong and lightweight design, CNCmachined for a precise fit, and individually inspected for quality assurance. The large 90mm throttle body opening, 81mm velocity stacks, and hivelocity intake runners with smooth transitions allow the Ultra Series Manifold to outflow the competition. Designed to be used with built, highhorsepower naturally aspirated or forced induction setups, the Skunk2 Ultra Series Intake Manifold helps provide a new level affordable highend intake technology to the marketplace. 1L and 2L Plenum Spacers upgrades available.
